in a word i would say "intresting"
i didnt relise so much work had been done (
http://www.handhelds.org/moin/moin.cgi/UniversalStatus), once the patches are merged with the mainline it looks like it will get a bit more hardware support (such as cameras)
i might just point out that handhelds uses an old fork of the kernel with ALOT of patches that are handy for testing, however it has lead to alot of work repeated around the place, last time i checked there were 3 cpufreq scaling patches, one on this fourm, one in the handhelds tree and one in the mainline (althogh the one here i belive got merged with the mainline)
i think the most important part on that site is this:

The phone is now working, we are able to make and receive calls (but still useless since we dont have a sounddriver). Have tried to send and recive sms but with luck.
We also moved over to kernel 2.6.18. I have tried it and it works as .17. When we are able to get the sounddriver solved we will reomve all .12 content. This is because the status of the 18 will be more complete than with .12, and AFAIK there will be no more working on the .12 sources.
so it lt looks like a merger with the mainline (so easy to compile yourself) and i belive that would allow for them to work with the embedded alsa stuff so that the driver will be written once and work with any device that uses the same sound chip (instead of a new sound driver for every diffrent model)
oh well thats my brief rundown of the technicals, hope you guys can find some more (perhaps a link to the mainingl ist where they talk about the call stuff ?)
