Yes, these are the relevant lines:

----
Kernel command line: ro video=radeonfb:1024x768-8@75
Console: colour dummy device 80x25
radeonfb: ref_clk=2700, ref_div=12, xclk=24975 from OF
Console: switching to colour frame buffer device 80x30
radeonfb: ATI Radeon 9000 If DDR SGRAM 64 MB
radeonfb: DVI port no monitor connected
radeonfb: CRT port CRT monitor connected
----

Hmm, I just noticed that it believes I connected a CRT monitor. It's wrong,
I have an non-Apple LCD display connected to the DVI port. 80x30 means the
resolution is still 640x480.

This a dir of /proc/device-tree/pci@f0000000, but I don't see how can it be
useful. Is there a tool to extract more info ?
