startx hard locks machine

[mlists <mlists@konjz.org>]

I'm trying to install OpenBSD on a A7V333 board with AMD XP 1800+ and
starting X hard-locks the machine every time. I've tried 3 different
cards so far, all AGP: Matrox G200, Riva TNT2 and Geforce 2 GTS. I
tried nv driver for NVidias, and also vesa and vga. The machine has 256
megs of PC2100 ram (1 chip), a hard drive and a floppy. I did a
network install off of my fileserver of 3.1-release, and 3.1-snapshot.
Also I did play with BIOS. Mailing archives, google and deja didn't
help much, the closest I got was that some nvidias on laptops had
problems, and they work with vesa, but mine doesn't work with any
driver. I don't have a PCI videocard to try at the moment, but I don't
understand wtf I'm doing wrong..Does anyone know what I can try next?
Is this a lemon board, some other hardware problem, or something else?
Thanks.
