Same problem here with Ubuntu 10.10 on an Acer Aspire One 522, which uses a Broadcom chipset (BCM4313).
My educated guess is that the binary blob Broadcom driver is to blame, so i guess this bug is kind of irrelevant post-natty because the 2.6.38 kernel includes an open source broadcom driver for this chipset.
