O.k., more testing, I've tried it out on another box, which has
a 3com network card and IDE disks, and it *doesnt* happen there.

Things the vulnerable machines have in common:

 SCSI hard-disks
 Software RAID 1 set-up
 GigE cards (bcm5700 , e1000)
 Dell (2650, and 1650)

Things unaffected machine has:

 IDE disks
 no RAID
 3c905 network card.

So unless both the bcm5700 and e1000 driver are affected, it's
probably not that. To test if it was the raid stuff, I moved
my stuff to a non-RAID scsi partition, and that didnt fix
anything. So I think that can be ruled out. I havnt got any
idea what's causing it, but bottom line, it looks less and less
likely that this is a bug with apache, and more like TCP_CORK
+ IPv6 is broken on some linux setups.
