Just pulled your version of 2.6.28, built and installed, and wanted
to let y'all know it's a great kernel (been running it since it came
out). Ext4 is working well for me so far, I don't need madwifi anymore
because ath5k is built in, the list goes on. You'll want to pick up the
beta nvidia-180.17 driver
(http://www.nvidia.com/object/linux_display_amd64_180.17.html) to go
with it. Works great for me (Amd-64 dual, nvidia 8600 gs). I found a bug
in cpufreq_ondemand.c and the author fixed it; that patch is worth
adding ASAP for people running niced processes.
Mail me directly if you want; I'm not on any mailing lists.
