Browsing through the kernel changelogs it seems that there were quite
a lot multicasting bugfixes between 2.4.17 and 2.4.26. e.g. this
changelog contains "PPC32: Fix a multicast bug in the MPC 8xx / 8260
enet drivers", which resembles your setup quite a bit, doesn't it?

It might be possible to set ALLMULTI instead of PROMISC for the
interface. This is less intrusive.

May I consider this bug report "closed" now, right?
