Actually, you can tweak the amount of buffers qeth allocates.
There is an obscure chandev parameter "memory_usage_in_k". Set this to
a tiny value and qeth will use the minimum amount of memory for its
inbound buffers (for example, try "qeth0,0xfd00,0xfd01,0xfd02,1")

It's not really the OSA code, it's the buffers. This was a problem I ran
into last month or so, when I noticed kswapd chewing up all my CPU. If you
look at the number of fixed pages with and without an OSA interface (real
or
virtual) you'll see what I mean. I would hope that this can become tunable
in the future. Not everyone is going to need the amount of buffers that
are
now the default.
