While there might be some other reason for this problem, it is fairly well
known that the ATI Mach64 cards can't work if sio3 is probed. I don't know if
you considered your serial ports "non-essential" or not, but ALL of them need
to be disabled for installation (sio0 - sio3). After installation you need to
compile a new kernel with no sio3 device AND you need to edit
"/usr/src/sys/i386/isa/sio.c" to change this line:
/* XXX - configure this list */
static Port_t likely_com_ports[] = { 0x3f8, 0x2f8, 0x3e8, 0x2e8, };
Into this line:
/* XXX - configure this list */
static Port_t likely_com_ports[] = { 0x3f8, 0x2f8, 0x3e8, };
While I have seen mention of new/old BIOS problems with the AHA2940, I have
two machines running FreeBSD v2.1.0 with them (and ATI Mach64 cards) here.
If you have already done the above, disregard (as if I had to tell you).
