Parallel Printing Problems in 2.1.105

I can't seem to print using the parallel port in linux 2.1.105, where the
same setup works in 2.0.33. [And no, this is not the lp1->lp0 change, I
know about that].

The computer is a Dell OptiPlex GXpro [Pentium Pro 200, 128meg Ram]. It
is connected via parallel cable to the printer, a huge, rather old,
Tektronix color wax printer. It serves the office, using lpd for unix
boxes and samba for the windows boxes. It functions just fine in 2.0.33.

I have tried flipping SPP/EPP mode in the Bios to no effect.

Under 2.0.33 the device is /dev/lp1

Relevant info under 2.1.105 [compiled as SMP on single-processor Machine]

I have tried it in both default polling mode and also on irq7. Neither
workse.

[on 2.1.105]:
orws5:/proc/parport/0$ ls
devices hardware irq

orws5:/proc/parport/0$ cat devices
lp

orws5:/proc/parport/0$ cat hardware
base: 0x378
irq: none
dma: none
modes: SPP,ECP,ECPPS2

orws5:/proc/parport/0$ cat irq
none

orws5:/proc/parport/0# cat > /dev/lp0
bash: /dev/lp0: No such device or address

orws5:/proc/parport/0# cat > /dev/lp1
bash: /dev/lp1: No such device or address

orws5:/proc/parport/0# ls -la /dev/lp0
crw-rw---- 2 root daemon 6, 1 Apr 27 1995 /dev/lp0

I have searched for solutions for a while and can't seem to find any. It
is annoying having to reboot into 2.0.33 whenever someone needs to print a
color picture ;) [2.1.x has nice features, like ntfs, dcache speed, APIC
code, and X doesn't crash if I move the mouse too soon after a vt switch].

The only thing left I will try is compile it as non-smp.

Any help would be appreciated.. thanks...
