If you set:

BISECT_TYPE = test
TEST = ssh user@host test_script

Where the test_script resides on the test target, and will exit with 0
on success and non-0 otherwise, it should work.

I could also change the code to give you access to the bootlog (actually
you already have it, but it's in the temp directory).
