Well, in that case, maybe we should steal their driver 8-)

I've used the interruptless version of the driver on my 5x86 box to print
stuff to my annoying PPA printer (an HP deskjet 712 that was paid for by
my fiancee's employer, so I complain not) without the system getting any 
slower than it already is (and believe me, that box is slow enough that
it would be hard not to notice..)

I've never used the interrupting one becuase of the horror stories I've 
heard about it rebooting x86 boxes and because I'm continually short of
IRQ's.
