I tried 3:

netbsd-2 netbsd-GENERIC.gz

	unexpected machine check:  (looks like the cmd pata controller problem)

netbsd-3 netbsd-GENERIC.gz

	hangs (same as custom below)

built custom kernel same as what I'm normally running, but without the osf fix
for netscape.  It has ehci configured.   current: kernel sources, config and genassym;
2.0.2: everything else (e.g. gcc)

	hangs:

Booted normal kernel, ran "scsictl sd16 identify" to verify that
the USB-PATA stuff was working, then tried custom current kernel
again, got the same hang.

So now, (back running normal 2.0.2 kernel) dmesg output is
mangled.  Some old USB output is mixed in:

umass0: BBB bulk-in stall clear failed, TIMEOUT
umass0, s/n 
8192 byte page size, 1 processor.
total memory = 256 MB
(ed, TIMEOUT
umass0: BBB bulk-out clear stall failed, TIMEOUT
ehc 246 MB

cpu0:ailed, TIMEOUT
umass0: BBB bulk-in clear stall failed, TIMEOUT
u Core Logic Chipset (Pyxis), pass 1
cia0: extended capabilities: 1<BWEN>

[ it goes on but you get the idea ]

The system has been rebooted at least 6 times with 4 different
kernels since those USB messages came out.  This only appears in
dmesg, the console output was fine.
