Check out MIB, the have just released [url=http://mib.pianetalinux.org/miblight/2009/02/03/kernel-26283]kernel 2.6.28.3[/url] which has full support for the AA1. I am using it now, and it seems fast and stable, with wifi working better than ever (the first time the ath5k driver doesn't crash here when seeing many APs with the same SSID). The wifi led works, suspend works (with /home in sdhc), boot is fast, a very good release in all.
