I received a question about support of PCI USB card,
so I'd answer it here.

GENERIC kernel of NetBSD/cobalt 5.1 doesn't have necessary drivers
for USB devices so it doesn't work by default installation.
NetBSD/cobalt itself supports PCI and USB devices and
we have to config and compile a new kernel from sources.

I know it's a bit annoying so I also put a compiled sample kernel
which includes much more PCI and USB device drivers:
ftp://ftp.NetBSD.org/pub/NetBSD/arch/cobalt/5.1/
- kern-GENERIC.tgz includes "/netbsd" kernel based on GENERIC
  but with more drivers.
- "PCIDEVS" is a kernel config file to build this one

You can use it by replacing a kernel in running your system and
rebooting it, but don't forget to rename an original kernel for recovery.

See also NetBSD guide to build a kernel from sources:

Note on-board VIA bridge chip has UHCI, but we can never use it.
(it's disabled and no connected signal lines)
