A brief look around has yielded the following links for arm-linux ports:
http://ftp.kelp.or.kr/pub/arm-linux/people/xscale/mainstone/04-28-2004/
This may or may not support all the devices of course but anything on the Mainstone dev board is likely to be explored.
Intel has stated that it will supply linux (power management at least) board support packages. See this list for comments on running linux on the Intel developer Mainstone board.

Montavista's announcement
http://www.mvista.com/news/2003/bulverde.html means that there is support though GPL issues might possibly exist.
There seems to be generic support in 2.6.7 but I doubt that all devices are catered for. Its reassuring to see a file arch/arm/mach-pxa/pxa27x.c
See Nico Pitre's comments on toolchain and compatability issues with 27x

Nico is also actively working on the kernel - see
http://www.ussg.iu.edu/hypermail/linux/kernel/0405.3/1471.html for pcmcia support in 2.6.7-rc2 in May for example.
Nico is also helping with other generic drivers - see
http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2004-April/021335.html
There is activity on the arm-linux mailing list too. See
http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2004-July/023442.html for an example.
I'll download 2.6.7 shortly (I'm on a dialup so it will take a while ...) and see what is current.
A comment on the off-chip storage issue. Using MMC/SD might be more general purpose than memory stick. There exist GPL drivers for 2 and 4 bit MMC interfaces and (I believe) there exists a GPL SD port despite the licensing problems that prevented it in the past - can anyione confirm this?
