Since saa7134-oss is factored out oss=1 doesn't work anymore for what I
know. Just modprobe saa7134-oss should be enough since auto enumeration
works fine.

tuner 4-0060: chip found  (at)  0xc0 (saa7134[3])
tuner 4-0060: type set to 5 (Philips PAL_BG (FI1216 and compatibles))
saa7134[3]: Huh, no eeprom present (err=-5)?
saa7134[3]: registered device video3 [v4l2]
saa7134[3]: registered device vbi3
saa7134[3]: registered device radio3
saa7134 OSS driver for DMA sound loaded
saa7134[0]: registered device dsp1
saa7134[0]: registered device mixer1
saa7134[1]: registered device dsp2
saa7134[1]: registered device mixer2
saa7133[2]: registered device dsp3
saa7133[2]: registered device mixer3
saa7134[3]: registered device dsp4
saa7134[3]: registered device mixer4

For autoloading something like this should do.

install saa7134 /sbin/modprobe --first-time --ignore-install saa7134 && { /sbin/modprobe saa7134-oss || :; }

You can't use saa7134-alsa and saa7134-oss at once. It returns EBUSY.

With Ricardo's fixes this is also fine again in mercurial now.
