I have installed from LawlessPPC-Leo-10.5.4-Phenom as well as all distro's other than Ideneb (that'll be the next try). Lawless installs fine, patched with NicholasBlocks kexts but first boot "waiting for root device". Can't get past there. If i try copying the extensions folder from DVD to HDD it gives Kernel error, and I dunno how to get past that one.

Also tried various boot flags, to no avail. I'm a software developer for my day job and have had Tiger and Leopard working on my old P4P800Se, but no success yet on the phenom!

GA-MA78GPM-D2SH
Phenom 9550
Radean HD3670
IDE dvd and HDD.

Solved:
cp -R /Volumes/USBThinggy/AppleATIATA.kext /Volumes/FearItself/System/Library/Extensions/
cp -R /Volumes/USBThinggy/AppleOnboardPCATA.kext /Volumes/FearItself/System/Library/Extensions/
cp -R /Volumes/USBThinggy/IOATAFamily.kext /Volumes/FearItself/System/Library/Extensions/

then
chown -R root:wheel /Volumes/FearItself/System/Library/Extensions
chmod -R 755 /Volumes/FearItself/System/Library/Extensions
kextcache -k /Volumes/FearItself/System/Library/Extensions

from DVD...

Then I had the loop on keyboard setup, solved with:
booted with -s option (in terminal mode)

/sbin/fsck -fy
/sbin/mount -uw /

/var/db

touch .AppleSetupDone
passwd
set a password for root account

exit

Turned on lan & sata, both working OTB, Audio may or may not have worked out OTB but patched with the 889a kext.
No support for my gpu in OSX yet.
