小東です。

カールを2.6.12.5にバージョンアップしました。
/etc/modules.confにはalias eth0 sis900の行を追加。
/etc/rc.modulesの/sbin/modprobe sis900はコメントアウト。

やはりifconfigの結果も変わらずでした。
そこで、IRQがどこで設定されているのかと思ったので
/usr/src/linux/drivers/net/sis900.cを開き、
認識されている"Trident Audio"のソース
/usr/src/linux/sound/pci/trident/trident_main.cと比較しました。

すると、tirdent_main.cの3585行でirqを設定している前で
request_irqを実行していたのに対して、
sis900.cは434行目でirqを設定しているが、request_irqを行っていないし
1003行目にあるrequest_irqではsis900_interruptのアドレスを渡していました。なので434行目のところにrequest_irq関数を追加し、1003行目の&をはずしました。
そして、リコンパイル。

すると
           CPU0       
  0:    1310925          XT-PIC  timer
  1:        816          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  5:          1          XT-PIC  ohci_hcd:usb1, Trident Audio
  8:          2          XT-PIC  rtc
  9:          2          XT-PIC  yenta, yenta
 11:          1          XT-PIC  acpi, sis900
 12:        110          XT-PIC  i8042
 14:       4372          XT-PIC  ide0
 15:         11          XT-PIC  ide1

「11」のところに、"sis900"の文字が出ました。
いけた！と思い、ifconfigしましたが、結果は変わらずでした・・・残念。

以下は他の設定値です。
