I'm having trouble installing a snapshot built 20000203 onto my brand
new laptop.  Hardware info:

Acer TravelMate 342T Intel Pentium III 500MHz w/ O2 Micro CardBus
slot, builtin Intel 8255x Ethernet + modem + externel combo
floppy/CD-ROM drive.

The installation appears to probe everything correctly, but hangs just
after printing the "biomask ... " line.  I built an unstripped install
kernel, dropped into the debugger after it hung, and got the following
stack trace.  Any ideas?  I don't know how to debug this.

	Thanks,
