Hi,
trying to remove the module i810_audio using 2.4.21-ac4
does reliably result in an oops:
Jul 1 10:00:35 legendre kernel: Intel 810 + AC97 Audio, version 0.24,
09:17:53 Jul 1 2003
Jul 1 10:00:35 legendre kernel: i810: Intel ICH2 found at IO 0xe800 and
0xec00, MEM 0x0000 and 0x0000, IRQ 10
Jul 1 10:00:36 legendre kernel: i810_audio: Audio Controller supports 6
channels.
Jul 1 10:00:36 legendre kernel: i810_audio: Defaulting to base 2 channel
mode.

Jul 1 10:00:36 legendre kernel: ac97_codec: AC97 codec, id: CMI97 (CMedia)
Jul 1 10:00:36 legendre kernel: AC97 codec does not have proper volume
support.

Warning (compare_ksyms_lsmod): module i810_audio is in lsmod but not in ksyms,
probably no symbols exported
