I wrote earlier that I was having lots of problems with 2.2.15preNN
on my laptop.
Basically, sound stopped working, pppd would die on certain
outbound data xfers, wireless ethernet stopped working.
I spent the weekend verifying that things did indeed still work with
2.2.13, and searching further for what was wrong.
I've narrowed the problem down to something in the pcmcia subsystem
(the add on one).
2.2.13 or 2.2.15pre11 with pcmcia 3.1.3 both work fine.
It is moving to pcmcia 3.1.11 that breaks things.
Basically, pcmcia 3.1.11 grabs irq 10 for itself (which is
hardwired in the laptop to the sound system) and starts
misusing it for itself, breaking the sound subsystem. It
further assigns IRQ 10 to the various cards that I plug in
and they then misbehave in various ways.
The identical hardware and configuration works fine under
3.1.3 and is broken in various ways under 3.1.11.
In both cases, the PCIC is configure to use polling and
interrupts 5, 7 and 9 for cards. (to quickly identify
the diffs below just search for '10' without the quotes)

Now I'm off the bother the linux-laptop people this problem.
Thanks for the help.
