I read about this ages ago.  I *think* it was windoze doing some sort of 
a shutdown on the card, disabling it or putting it into sleep mode if 
you want to call it that.  It appears that Linux isn't "waking" the card 
up but a power cycle does.  It also appears that windoze "wakes" the 
card up when it boots.

I'm pretty sure they found a fix but I can't recall what they did.  It 
seems they changed some sort of setting in windoze but not real sure.  
May want to google the mailing list archives and see if you can find 
it.  I know it is older than the archives I have here.  I keep them for 
a year then it dumps them.  So it's been a good while.  May have to dig 
back a while.

Biggest point of reply, you're not nuts.  Someone else had the same 
problem.  lol  Hard to believe I remember as much as I did tho.  o_O
