Yes, somewhat. The major blocker is a lack of interrupt support,
because the Altix doesn't have SAPICs. But before I can work on
interrupt support I need a driver that doesn't fail to allocate
DMA memory. This may need support for the I/O MMU. If so, that
I/O MMU support is the first blocker to resolve.

Other than that, FreeBSD boots with the changes (and kluges) I
have on the altix branch.

If you want to see if and how well FreeBSD boots on the 450, you
need to checkout svn+ssh://svn.freebsd.org/base/projects/altix,
build a kernel using the ALTIX configuration and boot that under
EFI. You also need to build a loader from that branch, because
the standard loader won't work. Devices won't attach, but you
should find all hardware and be asked for the root mount point.

FYI,
