The ppbus is documented by there was no entry in the GENERIC configuration 
file. This is the result after enable all currently supported devices:

atppc0 at acpi0 (PNP0401): AT Parallel Port
atppc0: io 0x378-0x37f,0x778-0x77b irq 7 drq 1
atppc0: FIFO <depth,wthr,rthr>=<16,8,8>
atppc0: capabilities=3f<INTR,DMA,FIFO,PS2,ECP,EPP>
ppbus0 at atppc0
ppbus0: No IEEE1284 device found.
lpt0 at ppbus0: port mode = 1<COMPATIBLE>
plip0 at ppbus0
pps0 at ppbus0

I'm trying myself in writing the missing ppi(4) driver. There is already a ppi 
device as part of the GPIB interface (/sys/dev/gpib). Any objections to call 
the new device ppio? Is there a specification for the ppi(o) device?
