FreeBSD 7.0 on AMD Phenom

[. .]

Hi, freebsd-bugs at freebsd.org mail group members.
I try to install fresh FreeBSD 7.0 for AMD64-platform on new Phenom-based computer.
Distributive was downloaded from ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-amd64/7.0/7.0-RELEASE-amd64-disc1.iso and nearest files.
MD5 and SHA256 checksum is correct.
Unfortunatelly, during boot from compact-disk BTX loader chashed with message:

CD Loader 1.2
Building the boot loader arguments
Looking up /BOOT/LOADER... Found
Relocating the loader and the BTX

BTX loader 1.00  BTX version is 1.01

Probably it performs due FreeBSD 7.0 is not supports AMD Phenom processor or such environment was not tested.
In this case my message is future request and I hope this modern processor will be supported.
Is there any workaround how to install FreeBSD on Phenom?
