Subject: [PATCH] intelfb: support 945GME (as used in ASUS Eee 901)
The following patch adds support for Intel's 945GME graphics chip to
the intelfb driver. I have assumed that the 945GME is identical to the
already-supported 945GM apart from its PCI IDs; this is based on a quick
look at the X driver for these chips which seems to treat them
identically.

The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
I'd be able to use it to get a console at the native 1024x600 resolution
which is not known to the BIOS. I realised too late that the intelfb
driver does not support mode changing on laptops, so it won't be any
use for me. But rather than throw it away I will post it here as
essentially "untested"; maybe someone who knows more about this driver,
and with more useful hardware to test on, can pick it up.
