How to see module errors on bootup?

[Kent West <westk@acu.edu>]

I know "dmesg" will show the boot-up messages generated (by the 
kernel?); however, this apparently doesn't show the errors generated by 
modules being loaded. These messages go by too fast to catch, and then I 
haven't been able to find a way to read them again.

Can anyone clue me in as to how I can get to these messages?

Thanks!
