My architecture is only superficially supported by the current
Linux-MIPS cvs, so coming up with a patch for that would be a bit
difficult right now.  (the current CVS appears to have some basic
support for the vr41xx processor, but that's it).  The codebase I'm
working with right now is a terrible mix of the (outdated) linux-vr
and (current) linux-MIPS trees, which means that I'm already going to
have big issues if I ever want to upgrade versions or whatnot.

I guess my current plan is to keep hacking until I get a system that
works acceptably well, and then start submitting small patches to the
linux-MIPS tree to try to incorporate all of the linux-vr-specific
stuff, which would hopefully eliminate the need for the linux-VR
tree (which is not being actively maintained anyway).

I currently have my PCMCIA drivers built into the kernel; the
kernel-based card services stuff seems to work just fine in
my case, so I don't need an initrd.  Having never dealt directly with
PCMCIA under Linux before, I didn't find this strange, but it seems
that other people find a cardmgr-free PCMCIA setup a bit strange. :)
