KGDB-enabled kernel on sparc64?

[Chris Ross <cross+netbsd%distal.com@localhost>]

  Is this known to be broken?  I see commentary about it, but don't  
know for sure that this is a known defect in the MD sparc64 code...  I  
see some comments about it in "ongoing projects" pages, but nothing  
definitive or particularly recent.

  Anyone know if this is a no-go?  Thanks...
