The traditional way is to connect a serial cable and direct console 
output to the serial port.  You can then cut and paste the console 
messages from a nice graphical buffer.

Other ways are proposed, such as crash dump to disk and network crash 
dump, but I don't think any have made it to mainline yet, though 
patches are available.  (More voices asking for it on lkml would help.)
