Hmmm.  I'm in much the same boat although I did upgrade to 5.2 since
starting to run the 2.2.x kernels.  I've got an HP550C that I've
been running off this box since back in the Slackware w/1.2.1 kernel
days.

After going to 2.2 I tried to make a go of it using modules but
modules still give me the screaming horrors sometimes.  I did have it
working with modules for a while with these lines in my conf.modules:

alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7

but it was fussy as all get-out and I couldn't rely on KMOD to
always load them for me.

I now have the parallel port compiled into my kernel.  I use make
xconfig.  Under General Setup I've selected 'y' for Parallel Port
Support and PC-Style Hardware.  Under Plug and Play Support I've
selected 'y' for Auto-Probe for Parallel Devices (even though I'm not
using any IEEE-1284 stuff).  Under Character Devices I selected 'y'
for Parallel Printer support and Support IEEE1284 status readback.

The system comes up and probes an lp0 device with no IRQ.  Under
2.0.36 is was probing at lp1 with no IRQ and I was using tunelp to
set it to IRQ 7.

When I cat /proc/parport/0/hardware I see:

base:   0x378
irq:    7
dma:    none
modes:  SPP,ECP,ECPEPP,ECPPS2

Nothing in lilo.conf, VIA MVP3 chipset, yadda yadda yadda.  And no
sound card, just my 4-port serial eating 5 and 9 with two ports
idle.

I had to go into /etc/printcap and change the lp= item accordingly.
