Alternatively, try using a post mortem dump of the lug buffer to  see
what  might  have  been prited to the console buffer. See the FAQ for
details.

I strongly recommend *against* doing this, at least unless  you  know
*exactly*  what  you  are doing (and then you don't need this because
you will use a BDI2000 anyway). I've seen to many reports  of  "Linux
crashes  when  enabling  the  MMU"  that  were  cause by exactly such
attempts.
