  Yes, I may say that the job you've already done is very impressive,
and aims you have are even more ambitious. If you do PalmOS, WinCE
will be next ;-).

  I really hoped to get response from QEMU author/ARM emulation maintainer
regarding these points. Paul, any comments? Would you be interested to
add more CPUs/boards? Any suggestion regarding this? Maybe if it is
expected that there may be many implementation and they won't fit into
core distribution, to provide API for plugin development?

  Actually, I'm also working on porting a PDA to run Linux (iPaq
4150/XScale). So far I don't have strong need to run kernel compiled
specifically for that device in QEMU, though SD support you
implemented seems like very good addition for emulation of any PDA
device. Anyway, I'm currently using Integrator/CP kernel from here:
http://www.o-hand.com/~richard/qemu.html , which boots h4000 userland
(Familiar Linux GPE) just fine. Well, that GPE image doesn't have
suport for mouse, and QEMU cannot emulate touchscreen. So, first thing
I'd be interested from your patch is that "absolute mouse" support.
Its status is also not clear - googling gives lots of references, and
over good period of time, but it seems that patch is still not in the
mainline?

  Well, I guess I need to look closer at you patch and try do my
builds based on it, before asking specific questions.
