And yesterday delphij@ have sent me patch against "firmware handshake timed
out".
It is attached. Can you please test it?

Hi,
A colleague of mine has found that BCM 5752 A02 would get "firmware
handshake timeout" problem during the ifconfig stage. After some
investigation and comparing to the Linux driver I have the attached
patch make the problem disappear. Unfortunately I do not have
specification documentation from Broadcom so I can not say if that is a
"real fix" :-(
The patch was tested on Dell Latitude D820. The only problem remains is
that the -CURRENT kernel crashes if I did not explicitly set the media
and do a "ifconfig bge0 up", with "panic: invalid ife->ifm_data (0xa) in
mii_phy_setmedia". Backtrace is available upon request.
Cheers,
