The dmesg ouput did show that intelfb was not able to acquire the EDID
from the BIOS, even if CONFIG_FIRMWARE_EDID=y I presume. I don't think
it's the VBE version, the chipset is an Intel 830 which should at least
be a VBE 2.0.
Is it the same for the working kernel? Do you have a link to the dmesg
ouput of a working kernel, if possible with #define DEBUG in
drivers/video/fbmon.c. The output of read-edid or /var/log/X?.log will
also be helpful.
