Did you set to ECP mode in your BIOS?

I've had ECP working in 5.1 & 5.2 using device.hints as I've been
misusing a machine as PLIP router to provide old laptop w/ network
since PCMCIA interface isn't working w/ installed kernel.

dmesg:
ppc0: <Parallel port> at port 0x378-0x37f irq 7 flags 0x8 on isa0
ppc0: Generic chipset (ECP-only) in ECP mode
ppbus0: <Parallel port bus> on ppc0
plip0: <PLIP network interface> on ppbus0
lpt0: <Printer> on ppbus0
lpt0: Interrupt-driven port
ppi0: <Parallel I/O> on ppbus0

device.hints:
hint.ppc.0.at="isa"
hint.ppc.0.irq="7"
hint.ppc.0.flags="0x8"
hint.ed.0.at="isa"
