just to share, what my experiences are:

- I have seen those reception quality issues only with rev 1.1.x drivers
(2.4 branch), never with 1.0.y.

- I had two boards that showed the problem in different PCs (mostly
PII/III 200/400 MHz class), but not in another (Epia 533). 

- The hardware fix did not change anything in the mentioned PCs.

- I've even moved thoses machines to another dish, without any success.

- It just happens with rev 1.3; 1.5, 1.6 and 2.1 run fine.

So in my opinion there must be another bug despite the hardware flaw.
