 very interesting. After cooling down the whole pile of junk I can
reproduce the transition problems with both D2 and D1 as the sleep
state. With D2 it is 100% reproducible, with D1 I had rare cases where
the adaptor survived the transition. Apparently something is very weird
with my notebook.

 Removing the module does not help in *most* of the cases. Meaning - I
had one case where removing the module helped.

 In order to play with the problem I have modified my initial "patch". I
have introduced an option "apm_sleep" that can take values between 0 and
3, with a default of 2, representing the levles D0-D3. Applies against
2.4.7-ac3. Adding the line:

option eepro100 apm_sleep=0

to /etc/modules.conf solves my problem. Without the line the default
behaviour is used. I do some sanity checking on the value of apm_sleep.
0-2 are tested, 3 most likely needs some work wrt. saving/restoring
device state.
