Mainly misspellings of the init_waitqueue_head stuff, as far as I
remember... They compile, but complain about unresolved symbols...

What I can imagine it being used for is user-space printer drivers for
weird WinPrinters that require precise timing or such...

Nope... Can't do that reliably with this device... (and the paride modules
don't do that anyway, do they?)

My fault. It seems that writing TO the device generates less load than
reading FROM it... And as I usually only read from the device on my Linux
box (and transfer to it using my college's windoze boxes), testing the
patch by writing to the device on linux was rather wrong :-(

So, I haven't seen any improvements, really. Sorry to say that, but my
only parallel port device can't utilise ECP, thus ...
