The TX49H2 core appears to be MIPS-III instead of MIPS-I like the TX39xx
series.  Does it have the "slightly different to other MIPS style"
coprocessor 0 registers that the TX39's had or is it more similar to
other MIPS-III style CPUs?

We also support cross-compiling with recent tools.  I'm not sure if
hosting on non-NetBSD hosts is fully working yet, but certainly you
can cross compile just about anything from a PC running NetBSD/i386.

What's the full list of drivers you need?  With NetBSD, you can pretty
much use any existing driver regardless of what port/machine the driver
was originally written on.
