I had tested twl4030 at 3.4 Mbps couple of months back and it was working fine
with current settings. It wasn't a rigorous testing though.

So you're saying there was *never* a need for that slowdown,
and everyone was just copying an existing buglet?
I know I didn't make time to test whether faster speeds
would work ... but had expected there was a reason, at
some point, for that detuning.
There was a need. But I think it should be fixed by now. I shall test
tw5030 with 3.4Mbit/sec on monday. Will report.
