Sound on iMac G5 (8,1)

[Charles Plessy <charles-debian-nospam@plessy.org>]

Dear all,

I tried a self-compiled 2.6.15-1 debian kernel which I patched to enable
sound support:

http://patchwork.ozlabs.org/linuxppc64/patch?id=3924

When I try to load the snd_powermac module (which crashes the machine on
non-patched kernels), I encounter the following error:

sorbet:~#  modprobe snd_powermac
FATAL: Error inserting snd_powermac
(/lib/modules/2.6.15sound/kernel/sound/ppc/snd-powermac.ko): Unknown
symbol in module, or unknown parameter (see dmesg)

dmesg says:
snd_powermac: Unknown symbol i2c_smbus_write_i2c_block_data

Any hint is welcome...

Best,
