	Unfortunately I don't, though I'm sure that the BIOS will be pretty much 
the same between the two versions since the laptops are identical.

	Personally, I'm working on getting both graphics cards to work WITHOUT 
having to mod the bios - I've got the Intel card working, though with kernel 
hacks etc. The NVidia card almost works I think, but currently the X server 
driver thinks that the primary card is in fact the Intel one and so doesn't 
try to initialise the correct one.  I'm hoping that this is the only issue, 
but since I wasn't that bothered about getting that card working I haven't 
looked in to it further yet.

	In the mean time, booting an old kernel in speed mode, then booting the 
correct one, lets you use the NVidia card with the NVidia proprietary drivers 
- that works fine.
