Oh no! So the SKnet problems with the 407e can no longer be seen as an
isolated case. Probably many Synology boxes are suffering from it, and
I was just lucky with my DS-101g+.

This is the default MAC, when no address is present in the ROM. But that's
perfectly normal.

Synology didn't put a ROM onto the board, but just wrote the MAC into
the Flash ROM. A driver will have to read it from there and set it.
Probably PPCBoot doesn't know how to do that.

In altboot it is done by read_mac_from_flash().

Hmm... either there is a bug in PPCBoot's network driver or PPCBoot
doesn't flush the cache after loading.

Or you are using the wrong load-address. Did you copy&paste from your
terminal? Then it is definitely wrong. The load-address has to be
0x1000000.

Otherwise I would inspect the memory after loading with PPCBoot's md command.
Maybe there was also a compare-command, so you could compare the data
loaded by Kermit.

Looks exactly like Oscar's 407e. Very frustrating. :|
