Since then I've upgraded to a patched (with the radeon ACPI sleep patch)
linux-image-2.4.16-4-686 4.4.  After some testing I've found that using
/etc/acpi/sleep.sh causes this problem, while a simple replacement
script that does

  /sbin/modprobe -r -s usbhid
  /sbin/modprobe -r -s uhci_hcd
  /sbin/modprobe -r -s ehci_hcd
  sync; sync; sync
  FGCONSOLE=`fgconsole`
  chvt 12
  echo -n 3 >/proc/acpi/sleep
  chvt $FGCONSOLE
  /sbin/modprobe -s ehci_hcd
  /sbin/modprobe -s uhci_hcd
  /sbin/modprobe -s usbhid

doesn't.

This no longer happens -- I guess that's because the kernel in Breezy
downgraded the ipw2200 driver from 1.0.4 to 1.0.1.
