Not necessarily; if it is _loaded_ then it will.

There is no such parameter. But ppdev is just a driver like lp: it
requires the parport module first, and to attach it to any parallel
ports you also need the parport_pc module.
If you have parport_pc already loaded, just load ppdev with 'modprobe
ppdev'. I think that there was a bug in the early 2.4.x series that
prevented ppdev from loading 'on demand' (i.e. when /dev/parport0 is
accessed), so perhaps that's all you need to do.
I would have thought that SuSE would have issued a kernel errata or
two since 2.4.4 though: have you kept your system up to date with

I'm afraid it isn't documented very well. But for use with VMware you
might want to take a look at
