Yeah - applied it to 072 (theres some incompatability on my system with 073 
and removable partitioned devices just now) and now KDE (3.5) pops up a 
desktop icon for the icon. I can open it fine.

However, when I try to "safely remove" it, my entire machine locks. I can 
still ping it, but I cannot ssh to it. Specifically when I do 
"eject /dev/sdb", the machine locks with the message:
"Kernel panic - not syncing: PCI-DMA: high address but no IOMMU". I don't 
think this is going to be HAL's fault though. I'll go and hassle the 
appropriate people. :)
