Wheeeh, am I glad to see these patches.

Another thing I would like to see in the generic code is an interface
to register serial drivers instead of the current approach where every
serial driver is assigned its own major.

I see no reason for wasting all these majors on this and IMHO it is a
lot better to use dynamic allocation of serial devices, thus if one
replaces a serial board with a different brand it is not necessary to
go and change the entire software setup. I know this doesn't matter so
much on PC's where 99% of the serial boards are 16cx50 compatible, but
on systems where the serial boards are totally different this is a bit
annoying.
