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
Ah, now I know, I've seen your commits on handhelds.org!
There is a person working on PXA (I think 270) emulation in QEMU, but
I think they're at implementing the CPU now and out of the other
hardware there's only the serial port, but I don't know the details. I
only remember the person's nick on IRC.
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.
The absolute mouse support in my patch was basically stolen from
Anthony Liguori's early Wacom tablet patch. There are links to this
patch in list archives, I'm not sure if it's integrated into QEMU yet,
but there's a pointing device using absolute coordintates known as
usb-tablet which is in the mainline already.
I've been running GPE in QEMU as well, using mostly unmodified fs
images from familiar.handhelds.org and SD emulation which you
mentioned (IIRC I had to disable udev everytime). I took some
screenshots which can be seen at http://zabor.org/balrog/palmte/
(filenames ending in "-emulator").
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.

Good luck with your port.
