It's generally a very bad idea but I think it doesn't usually result in 
damage.  It's definately possible, for instance, to kill a PCI card by 
removing it while it's on (though I've even intentionally done things like 
that and ever seen any damage result from it) but I don't know if that would 
apply to ROM cards.  I would imagine things should be okay after a an 
initialize procedure.

There's probably a reset procedure detailed in the manual.  Or in the 
service manual.  I don't really have the time to check right now.

Can you give any more details (well if you fix the problem it's kind of 
irrelevant..)?  Is the display showing anything?  can patches be changed (at 
least visually, on the display), are LEDs illuminating normally, etc?
