swsuspend still breaks 3c905, 2.6.7

[David Ford]

Suspend and the 3com card becomes useless.  Have to remove the module or 
reboot. Seems to be a pretty common and long-standing bug with the power 
management and has been around since at least the middle 2.5.xx 
kernels.  And it seems it's also in 2.4.x.
