Hi Arnd,
I didn't review the patch thoroughly, but I launched your 2 patches in my pxa
little farm.
The result is that lubbock and mainstone are all right, but zylonite is broken
(ie. networkless). I removed then these 2 patches and zylonite worked again.
I have also an error message on the console on a "broken" zylonite :
Changing smcs91x MAC address to 08:00:3e:26:0a:5b: ifconfig: SIOCSIFHWADDR:
Device or resource busy
I reran the test twice (2 times with your patches, 2 times without), the result
looks consistent, ie. zylonite doesn't really like them.
Cheers.

PS: even if zylonite defconfig is not in the tree, it uses this driver, with :
CONFIG_SMC91X=y
...and...
static struct smc91x_platdata zylonite_smc91x_info = {
.flags = SMC91X_USE_8BIT | SMC91X_USE_16BIT |
SMC91X_NOWAIT | SMC91X_USE_DMA,
};
