I've been having the same problems for a long time with two different Mini-PCI cards (AR5416 & AR9160) on Debian 5.0 w/ kernel 2.6.32, with various hostapd and compat-wireless releases (latest combination being hostapd 0.7.1 / compat-wireless 2010-01-26). 

Both cards have similar issues where hostapd permanently stops transmitting beacons from between 10mins to just over 24hrs. There's absolutely nothing in any logs to suggest issues. I can however restart hostapd and the problem is immediately resolved.

I'm more than willing to collect logs too if pointed in the right direction.
