11.10 slow graphic performance with ATI switchable graphics when using Virtualbox

I am using 11.10 (on Virtuabox) on a brand new Samsung Series 7 with switchable graphics, which I am assuming that could be part of the issue here.

The graphics card is integrated Intel / and an ATI 6750M with 1 gigabyte of VRAM. I have Virtualbox (on Windows 7) set to the Maximum Performance setting so that it always kicks on the ATI card. I have Virtualbox set to use 128 MB (the maximum) of VRAM.

Almost all of the graphics are slow, if I launch Terminal it will take 5 or 6 seconds to even launch. If I type into the terminal, it will take 5 seconds or so for the characters to appear.

Has anyone else had any issues with this?

After more research, it looks like the issue is (surprise, surprise) with the switchable graphics. Even after instructing Catalyst Control Center on Windows to always use the dedicated Radeon, it still uses the integrated Intel GPU. To say I am not happy with Samsung at the moment is a complete understatement.....I paid for a discrete GPU, now I can't use it? This is apparently a widespread problem.
