PCMCIA subsystem seemingly dead on Breezy install

[Matthew Carpenter]

hi all,

Yesterday I had my laptop power down and when it came back up, PCMCIA was no 
longer working.  The one slot showed up to the OS, but when I plugged and 
unplugged cards, nothing happened.

Then I remembered setting my memory down.  I recently upgraded to 1GB RAM, 
which was more than my SWAP space.  This is important because after 
upgrading, Suspend to Disk took on a level of risk that makes Vegas look like 
a good bet.  So, to attempt to lessen the workable memory to squeeze inside 
the 960M SWAP partition, I added "mem=940M" to my kernel boot line in grub.

Since removing that line makes my PCMCIA subsystem operate correctly again, I 
can only assume that this parameter is what broke it.  Can anyone share why 
this might be?

Thanks!
Matt
