ppc fails to attach to puc on 9.1-STABLE, 7.4-STABLE works

[Andre Albsmeier]

I want my printer port back on 9.1 ;-(

I have this card:

puc0 at pci0:4:1:0:        class=0x078000 card=0x00121000 chip=0x98359710 rev=0x01 hdr=0x00
    vendor     = 'NetMos Technology'
    device     = 'PCI 9835 Multi-I/O Controller'
    class      = simple comms

It attached and worked under 7.4-STABLE (as long as I disabled
the interrupt using hint.ppc.0.irq=""):

puc0: <NetMos NM9835 Dual UART and 1284 Printer port> port 0xdf00-0xdf07,0xde00-0xde07,0xdd00-0xdd07
,0xdc00-0xdc07,0xdb00-0xdb07,0xda00-0xda0f irq 17 at device 1.0 on pci4
puc0: [FILTER]
uart0: <Non-standard ns8250 class UART with FIFOs> on puc0
uart0: [FILTER]
uart1: <Non-standard ns8250 class UART with FIFOs> on puc0
uart1: [FILTER]
ppc0: <Parallel port> on puc0
ppc0: Generic chipset (ECP/EPP/PS2/NIBBLE) in ECP+EPP mode (EPP 1.9)
ppbus0: <Parallel port bus> on ppc0
lpt0: <Printer> on ppbus0
lpt0: Polled port


Under 9.1 the card does not attach the ppc anymore. The hint entries

hint.ppc.0.at=puc0
hint.ppc.0.irq=""
hint.ppc.0.flags=0x2F

get ignored and so it probes as ppc1 (failing due to the interrupt
problem as it was in 7.4 without hints):

puc0: <NetMos NM9835 Dual UART and 1284 Printer port> port 0xdf00-0xdf07,0xde00-0xde07,0xdd00-0xdd07
,0xdc00-0xdc07,0xdb00-0xdb07,0xda00-0xda0f irq 17 at device 1.0 on pci4
uart2: <Non-standard ns8250 class UART with FIFOs> at port 1 on puc0
uart3: <16550 or compatible> at port 2 on puc0
ppc1: <Parallel port> at port 3 on puc0
ppc1: Generic chipset (EPP/NIBBLE) in COMPATIBLE mode
ppc1: failed to register interrupt handler: 6
device_attach: ppc1 attach returned 6

Any ideas? How do I construct the hint entries under 9.1 so that

1. it does not want to use the interrupt (which made it attach under 7.4)
2. it takes the flags 0x2F as it did before.

I have also never understood if ppc itself needs to attach to
the irq as well (I thought this all would be handled by puc).

Thanks,
