It seems this new AHCI chipinit is too robust for my box ;]
I just switched to HEAD and suddenly the system won't boot at all. 
I even compiled a new GENERIC with no results.
Thanksfully I had a backup GENERIC somewhere so that I could boot
without having to restore it from the livecd..

I get panics at the AHCI IDE disk detection routine. I don't remember
the exact function, but I can reproduce it and get more info, if needed.
This is my dmesg disk-related output, taken with the backup GENERIC
kernel:

atapci0: <GENERIC ATA controller> port

IIRC, the panic occurs just after this message.
I'll come back with more information, if asked.

Best regards,
Cristi
