Oh it certainly supports 32-bit mode - but I'm guessing it isn't
selecting the right mode at startup. Before the intel_extreme driver
worked with the laptop, I had to use VESA instead, and it always
started up in 8-bit mode requiring me to change it after the first
boot. (you even asked me when we met in Mountain View why I was
running 8-bit instead of 16 or higher... it was simply the default
that was detected)
So, I guess this maybe comes down to EDID issues. Strange that I'm
having this problem only with the intel chips - as the same CRT
monitor seems to work fine with a Radeon card on the desktop machine.
So, should the VESA driver try to find the highest supported
resolution with 15bpp or higher from EDID then?
I can provide the serial log from both machines in a ticket and see if
anyone can make heads or tails out of the EDID info.
