[Patch] 2.6 support for the Palm LifeDrive

Working:
- full boot (ie I can start busybox via an initrd)
- pxa framebuffer
- serial console

Partially implemented:
- USB (yet to find the GPIO to activate USB with)

Also, this patch includes a bunch of new mach-types from 
http://www.arm.linux.org.uk/developer/machines/ (including the 
LifeDrive, of course). I didn't include the several machs that were 
renamed however, as I didn't want to break any code that relied on the 
old names.
