Undoubtly a very old NT version, because NT doesn't support alpha
since years.
FreeBSD4.x memory load is also much less than that of 5.x.
Well - I did run -current on a 64M alpha only a few weeks ago, but with
a custom build kernel and without the install image loaded into a
memory disk.
Nevertheless - even if this is the cause we should at least get a
meaningfull error message instead of this panic.
