Sorry,

	The PCDig HAS the scatter-gather table, so the transfer is done in
	hardware. (no additional irq's)
	The IC-PCI (and PCVision) has NO scatter-gather table, so EVERY
	page transfer is done by the interrupt handler.

...with a PCDig you are on the better side of live...

OK, you are right. I have forgotten it, because line scan cameras are not
our business. I try to reimplement it into one of the next versions...
