Alsa driver not loading

I lost sound with my Audigy Gamer, chipset 3mu10k2, which uses driver
emu10k1. I am running debian sarge with kernel 2.4.27-2-386. Since the
sound worked, I have only upgraded packages, including the kernel.

Discover and lspci -vv see the card as:

  0000:02:0c.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)
        Subsystem: Creative Labs SB0090 Audigy Player
        Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
                Stepping- SERR+ FastB2B-
        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
                <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32 (500ns min, 5000ns max)
        Interrupt: pin A routed to IRQ 5
        Region 0: I/O ports at df80 [size=32]
        Capabilities: <available only to root>

The return from dmesg is:

  Creative EMU10K1 PCI Audio Driver, version 0.20, 16:51:53 May 16 2005

However, alsaconf does not see the card, and lsmod indicates the snd*
drivers are not loaded. In fact the loading fails:

  # modprobe emu10k1
  /lib/modules/2.4.27-2-386/kernel/drivers/sound/emu10k1/emu10k1.o:
        init_module: No such device
  /lib/modules/2.4.27-2-386/kernel/drivers/sound/emu10k1/emu10k1.o:
    insmod /lib/modules/2.4.27-2-386/kernel/drivers/sound/emu10k1/emu10k1.o
        failed
  /lib/modules/2.4.27-2-386/kernel/drivers/sound/emu10k1/emu10k1.o: insmod
    emu10k1 failed

The module does exist, and in /etc/modutils/alsa I have among other liness:

  alias snd-card-0 snd-emu10k1

and in /etc/modutils/alsa-base there is among other lines:

  post-install snd-emu10k1 /lib/alsa/modprobe-post-install snd-emu10k1

I assume the return from lscpi -vv suggests that the card is using IRQ5,
but $ cat /proc/interrupts reports:

  1: 1152627 XT-PIC keyboard
