I would check the boot configuration. Kernel 2.4.0 doesn't seem to support VESA framebuffer modes, it provides an option fro VGA and extended VGA only. There is new mechanism in place which drivers have yet to comply with. More in kernel documentation, I don't remember the details from the top of my head. If you use lilo, check if /etc/lilo.conf has vga parameter set to some high value ( like 781, or 0x305 ) indicating framebuffer modes and change it to vga=1, rerun lilo, etc ... I got a blank screen as well on my T20 ... Jacek
