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. Tony
