I posted working early serial patches as part of an earlier uartlite
driver (not PK's)
http://ozlabs.org/pipermail/linuxppc-embedded/2006-January/021545.html

The patch is a single big patch with compete board support for the Pico
E12 cards,
but it includes complete boot2bash uartlite support, including early serial.
The uartlite code much more closely follows the 8250 code.
The early serial portions probably would work asis with PK's driver. 
Though I can't confirm that as PK's driver does not work on my hardware.
A newer version of the same big patch is at
http://www.picocomputing.com/software/files/Installers/coLinux/Pico-2.6.patch.bz2
When I have more time and am more proficient with git I will likely break
it up into individual pieces.
