Just keep in mind these things:
1.) To prevent the "blank screen" that most new 2.6 kernel users often get on their first build, make sure that the following options are enabled:
# Graphics support
# Console display driver support
# Logo configuration
Note: these settings are not default in 2.6 and often do not carry-over properly from the 2.4.22 config file and must be double-checked!
Did you try that reply? (Posted by Jymbo but can't figure out how quote works on vbb =/)
I had the same problem with Slack 10 and 2.6.7, and found that I had to manually add those to my conf file but after following that, I got rid of the blank screen.
