Subject2.6.20-rc4 sky2 unsupported chip type 0xff / phy write timeout

Hi,
i have random problems after fresh boot with the onboard sky2 on an
Fujitsu Siemens Lifebook E8110. With 2.6.18-686-3 from the Debian repository i see
random crashes on boot - see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=404107

With a

Linux machine 2.6.20-rc4 #0 SMP PREEMPT Mon Jan 8 15:18:15 CET 2007 i686 GNU/Linux

i dont see crashes now but instead i see on random boots:

[ 12.412000] ACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 16 (level, low) -> IRQ 16

Afterwards the interface is not usable as one would have expected. rmmod/modprobe later:

[ 186.536000] sky2 eth1: disabling interface

[ 190.464000] sky2: probe of 0000:02:00.0 failed with error -95

On a working boot i see:

[ 12.236000] PCI: Setting latency timer of device 0000:02:00.0 to 64
