Whether it's a MicroVAX or VAXstation is checked in locore.c. This check
is erroneous for most machines, don't care so much about it.

You must have HW docs to know how to enable the cache. It is very
CPU-specific.

Not AFAIK.

Sort of. lkc is only found if the machine is a (as previously checked)
VAXstation. There are no real check for any keyboard.

That should work. The problem may be that it hangs in the timer 
interrupt following the enable of the clock. Eventually you can try to
use generic_clock() instead.
