855resolution patch and linux framebuffer
I have been working recently with the framebuffer driver vesafb and kernel 2.6.14. I am using the Intel 855GME chipset on a dell 700m laptop. The native resolution of the LCD on this device is 1280x800 - but can only be achieved after using Alain Porier's 855resolution patch to enter the correct mode into the chipset's BIOS. The sad thing is that I have to do this on every boot - and thus I have to run it before I load the vesafb driver. This procedure is undesirable. Is there a way similar functionality of this 855resolution patch could be integrated into the kernel in some way?
I think it would be very useful for everyone who is using this chipset and is dealing with having to enter modes into the BIOS in similar fashions.

It would require BIOS calls, and we don't have any facility yet to make BIOS calls in the kernel.

Would you, or anyone else be able to recommend an alternative?
Thanks
