I had sent this message to -stable about a month ago, never heard anything
-- so am trying it here.

OK -- I give up.... I'm trying to get the LPBB I2C driver working on my
3.2-stable machine, CVSUP'd earlier today... I have tried about a zillion
and two different config file combinations, and can not get it to work.
The relevant parts of the config file are:
device ppc0 at isa? port? tty irq 7
controller pcf0 at isa? port? irq 5
controller iicbb0
controller smbus0
device smb0 at smbus?
controller ppbus0
#device lpt0 at ppbus?
#device ppi0 at ppbus?
device lpbb0 at ppbus?
controller iicbus0
device iic0 at iicbus?
device iicsmb0 at iicbus?
(.....As you can see, I took out the printer driver and the geek port
during this hair-pulling session -- those two devices vanish, but nothing
else appears.)
The dmesg chunks that show up about this are:
ppc0 at 0x378 irq 7 on isa
ppc0: Generic chipset (NIBBLE-only) in COMPATIBLE mode
...
pcf0 at irq 5 on isa
...
pcf0: <PCF8584 I2C bus controller>
iicbus0: <Philips I2C bus> on pcf0 addr 0xaa
iicsmb0: <I2C to SMB bridge> on iicbus0
smbus0: <System Management Bus> on iicsmb0
smb0: <SMBus general purpose I/O> on smbus0
iic0: <I2C general purpose I/O> on iicbus0
It seems to see the PCF8584 just fine, but it refuses to put the parallel
port I2C interface in... If I remove the "controller pcf0" line, all of
the I2C drivers disappear.
Any ideas?
