The work Cedric is doing on his qemu fork is quite interesting, if we
can convert landisk to device tree and get that tree to cedric for
reference, he might be able to get qemu to emulate it.

A board with more than 64 megs of ram and a single hard drive would be
nice. (And a battery backed up clock.)

And, of course, teaching QEMU to emulate the serial buffer the kernel's
expected it to have for a year now. :)

Paul Mundt was not acting in the best interests of the Linux kernel.

If Rich doesn't find time by about February, poke me. (I'm in Tokyo this
month, then relatives for the holidays, then catching up from all that...)

Can these be ordered on amazon, or only bought personally in taiwan?
