i guess he is quite busy now to prepare the latest patches for 2.5
kernel.

si7012 is still supported.  the array above is the list for joystick
supports :)  the pcm should work:

static struct pci_device_id snd_intel8x0_ids[] __devinitdata = {
	...
	{ 0x1039, 0x7012, PCI_ANY_ID, PCI_ANY_ID, 0, 0, DEVICE_SIS },	/* SI7012 */
	...
};

most likely the driver was built with the incompatible kernel tree.
please check whether you installed the correct kernel-source package
and configure points the right directory (you can pass the directory
via --with-kernel option).

or, it could be a problem of rc3.  i've never compiled with module
version.  could you show which symbols are missing?

also, please note that on some distribution such like SuSE, you need
to overwrite certain kernel header files to match with the running
kernel.  for example, in the case of SuSE, /boot/vmlinuz.autoconf.h
and /boot/vmlinuz.version.h must be renamed and copied to
/usr/src/linux/include/linux, if you use an SMP kernel.

i'm not sure how about on mandrake, so cc'ed to Thierry.


ciao,

Takashi
