Thanks very much for the suggestion Yves; unfortunately it doesn't
seem to help though.  I've compiled the floppy driver as a module, but
I still experience the problems even without insmod-ing the floppy
module.  (I also put the "floppy=thinkpad" option in lilo.conf, just
in case.)

I've narrowed the problem down to PCMCIA.  If I boot without starting
any PCMCIA services, APM works fine.  However, if I even do

   /etc/rc.d/init.d/pcmcia start
   /etc/rc.d/init.d/pcmcia stop

without any cards inserted, then resume from suspend still slows the
CPU to a crawl; in fact sometimes it even fails to resume (i.e. hangs
completely).

I've moved to 2.3.3ac3, and the same problems are there (not that I
had any reason to suspect that a newer kernel would fix it).

I'm going to post the problem to the PCMCIA/APM list now ... I really
hope someone has an idea on this because I'm getting desperate!
