Device or resource busy

Hi,

I have a IBM ThinkPad T30 and installed Debian Woddy (2.2.20).
Ethernet worked fine out of the box.
Then I compiled an new kernel and added apm, sound etc. and now the ethernet 
card does not work anymore:

PRAG:/home/gh# modprobe eepro100
/lib/modules/2.2.20/net/eepro100.o: init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including 
invalid IO or IRQ parameters

 Use '-a' or '-aa' to show device registers,
     '-e' to show EEPROM contents, -ee for parsed contents,
  or '-m' or '-mm' to show MII management registers.

  No interrupt sources are pending.
   The transmit unit state is 'Idle'.
   The receive unit state is 'Idle'.
  This status is unusual for an activated interface.

  Station address 00:09:6B:7A:CC:CF.
  Board assembly 000000-000, Physical connectors present: RJ45
  Primary interface chip i82555 PHY #1.
   Sleep mode is enabled.  This is not recommended.
   Under high load the card may not respond to
   PCI requests, and thus cause a master abort.
   To clear sleep mode use the '-G 0 -w -w -f' options.
