I will assume then that the lsmod output you showed before was
incomplete and that ppdev probably was there after all (2.4.13 has the
ppdev-doesn't-load bug fixed already).
There is a VMware bug that has been identified that might be catching
you out here: although it doesn't use the kernel for parallel port
access (it just writes to the ports directly), it _does_ use it for
detecting ports in the first place. However, it makes the mistake of
asking the kernel what hardware transfer modes it will use, rather
than doing its own probing to find out what hardware transfer modes
are available (regardless of whether or not the kernel will use
A bug in kernels before 2.4.13 meant that the kernel would advertise
more hardware modes than it would actually use (for example, ECP when
there is no interrupt configured; the parport_pc implementation relies
on interrupts to use hardware ECP support at the moment).
Unfortunately, in fixing this bug IRQ probing got broken. I have sent
a patch to Linus to fix it, and it is in 2.4.13-ac2 onwards.
A workaround should be to specify the base address and IRQ line to
parport_pc. See Documentation/parport.txt for how to do that.
