pci sleep mode disabling 0n 82559..

Hello,

I am getting "wait_for_cmd_done timeout " messages 
while  using eepro100.c v 1.09j-t (9/29/99) and revision 1.1.1.5 for 
82559 card.

after browsing the mailing list i found that it might be possible because
of pci sleep mode enabled which was detected after eepro100-diag.c
diagnostic programme.

but since I have just completed my BSP and i am using a precompiled
busybox  ramdisk hence I want to disable the pci slep mode explicitly from
within my driver.

How can i do this..? 

Best Regards,
