Compiled 2.6.2-ben1-hermione today. Everything worked on first try (I installed module-init-tools, and added agpgart, uninorth_agp, and radeon to my /etc/modules – the order is important), except wireless. Load sungem before airport, and all is well – wireless was eth0 otherwise. Hard disk blinking light on activity patch from benh doesn’t apply (but that’s because the patch is merged and needs to be enabled in your .config file).
It’s not the fault of Yellow Dog Linux’s installer. Apparently, anaconda barfs when it sees Apple’s HFS+. So its time to wait for new ISOs, that has the “fix”. So there is hope, after all, to get YDL on cho.
