[prism54 driver] Can't connect to AP on channel 13

Bug Description

One of my neighbors bought an AP, and put it on channel 6, next to mine. Because
this brings down my data rates considerably, I decided to move to another
channel. Because most products in Europe don't support channel 13 even if they
can, I figured it'd be safe.

After switching my AP to channel 13, I suddenly couldn't connect to it anymore.
My card (SMC 2835W, prism54) started "channel-hopping": every time I ran
iwconfig, the channel would be different, and it didn't seem to be possible to
connect to the network.

"iwlist eth0 scan" DOES tell me there's an ap on channel 13 available, and if I
use another card (SMC2632-V2, using atmel_cs) I can connect to it (after running
'iwpriv eth0 regdomain europe', because it defaults to US for some reason)

Does it work if you force the card to channel 13? (iwconfig ... chan 13)

I confirm that this problem still exists in linux-2.6.17.11 .
I'm having this problem right now with SM2835W card.
I also tried all firmwares i could find up to 1.0.4.3 .
