The standard GENERIC kernels do work with at least some of those
'21143 with non-standard SROM' Cobalts.

I can only assume that the one you have is somehow a variation.

It would be helpful to know what exactly the PCI configuration space
and SROM contents look like. This can be done by adding 'option
PCI_CONFIG_DUMP' to the kernel and having tlp_parse_old_srom() in
sys/dev/ic/tulip.c print out the SROM.

If you do it with -current, cross-compiling should be very easy,
regardless of the type of system you are doing it on.

I suggest you try it out and post again if you have problems.
