There maybe something weird with the disk. A dmesg would be helpful but that's kind of hard to get if you can't get the boot-loader to work.
If you can format the fdisk/format the disk using a linux live cd or something. Another method would be to DD the first MB of the disc and reboot. You need to reboot to refresh the in-kernel geometry, not sure how to reload the kernel config without rebooting or hot plugging the disk.
My other suggestion would be to try another drive if you have one around. The motherboard in question has no FreeBSD 7 dmesg submitted but it seems to work with 6.2 (there were huge disk related changes between 6.2 and 7 so no assumptions can be made there).

Yeah you can tell sysinstall to disregard the in-kernel geometry but I've only had that work once. It pretends the drive is ok but is misaligned and the boot record isn't in the right place not to mention even if the boot loader worked, mount would freak out about it.
