crippling repeating "pciehp card not present" notifications

When using ubuntu (12.04, both installed and on a live usb) I get a lot of these messages:

pciehp 0000:00:1c.5:pcie04: Card not present on Slot(37)

pciehp 0000:00:1c.5:pcie04: Card present on Slot(37)

And with a lot I mean about 20 per second. This has a crippling effect, and I would like to get rid of it :)

The computer is a packard bell easynote BG48-U-100 DC.

I tip I picked up from some fedora/redhat error here was to look at lspci -vnn. I have pasted the part about "00:1c.5" here: http://pastebin.com/0sfsiqW2
For what good it may do, here is the lsmod of my machine: http://pastebin.com/DQZy1kAL

From that first pastebin I think to conclude that it has to do with the module shpchp, which seems to me (aka: google) to have something to do with ACPI. That's as far as I've come in disecting this.

Can anyone help me along further? What can I do, check etc?

I did see this topic but my intentions are not to surpress the error message: I know how to do this (from that topic ;) ), but I'm looking for a real sollution.

_{Finding the problem on the internet does suspect me to believe it is neither an ubuntu specific nor a packard-bell specific problem.If you google the problem it seems that is present on several other distribution/hardware combo's as well, and it looks like the advice is to remove one of the drivers? I have no clue as to which driver I should look at and and what would be the effect of just removing it.}

_{I have seen this topic which is old-ish, but describes my problem and is about a similar computer. The solution in this topic was to compile a new kernel using a spanish guide, which seems a bit extreme to me, so I'm kinda hoping for a better solution than that.}

edit: I just tested on 12.10 which still has the problem

On the account of surpressing: I can surpress it in the syslog, but the IO still goes on. I do also see the mentions in dmesg, and in one of the consoles. Even a way to surpress all these things would be a help at this point.

Another test also shows that a quick Fedora boot has the same issues on this machine

I tried the following patch-methods, and listed why they didn't work for me:

Bios features: nothing I could do in the bios would effect the hotplug problems I have.

Suppressing errors. The blacklist didn't reliably work for some reason (I might have done something wrong, I admit) and as I said, it isn't a real sollution. The polling still would've been going on. Apart from that, the messages would also show up in the tty's, in the DMESG, etc.

Unloading modules: the modules were compiled into the kernel, so blacklisting or unloading those doesn't work.

In the end I did compile my own kernel, using this manual:

https://help.ubuntu.com/community/Kernel/Compile

and specifically the "alternative" method. There is no need for all the fancy different flavors if you just need to remove one thing, so I copied my old config (as explained), removed the hotplug stuff, and waited for the compile to complete.
