FreeBSD 2.1.0

No special setup that I am aware of.  After setting LBA in the BIOS
and then booting the install disks everything worked automatically.

At boot time I see:

wdc0 at 0x1f0-0x1f7 irq 14 on isa
wdc0: unit 0 (wd0): <WDC AC31600H>
wd0: 1549MB (3173184 sectors), 3148 cyls, 16 heads, 63 S/T, 512 B/S
wdc1 at 0x170-0x177 irq 15 on isa
wdc1: unit 0 (wd2): <ST3491A-XR>
wd2: 408MB (836070 sectors), 899 cyls, 15 heads, 62 S/T, 512 B/S

ie the full number of cyls/heads/sectors but DOS etal see LBA and
can use the whole disk.

I'm not an expert, all I can see is it works for me.

See above, use two hd controllers (wdc0 & wdc1) with wd0-wd4 hanging
off them.  So yes.
