[PATCH] fixup pcnet32 workaround xSeries250

[Go Taniguchi <go@turbolinux.co.jp>]

Hi,

I have sent the update patch for pcnet32 which included the workaround for xSeries250 
on the other day.

However, the workaround has the problem with 79C970A 10M full duplex cards 
which causes the netowrk slowing-down.
To solve this problem, the workaound is set to be turned on for "79C975" only.
Please apply.

-- GO!
