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.
