I am happy to say that my patches to the standard serial driver which
were developed on LinuxPPC are in the latest 2.3 tree. Apart from making
it run on LinuxPCC, generic support for PCI cards was added, based on
work from various programmers (including myself ;-) )

I have a version of the new serial driver that works on 2.2.10/LinuxPPC
available as standalone module, if anyone is interested.
