I hate to be one of those "'does not reproduce" guys but;
Sadly I am unable to reproduce this. modprobe parport_pc doesn't seem
to make any complaints on my desktop.

lspci:

00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM
Controller (rev 02)
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express
Integrated Graphics Controller (rev 02)
00:03.0 Communication controller: Intel Corporation 82G33/G31/P35/P31
Express MEI Controller (rev 02)
....
I do find it quite odd that a DMA code path specific to PCIE is somehow
in the loop for a parallel port device. Should this be possible?

I could easily be wrong so feel free to correct me but;
I think your bios is goofy / unprepared to support IOMMU / VT-d and
doing strange things with enumerated a parallel port on a PCIE bus with
VTD is turned on...
