On my machine, with 1.2.9 kernel, alt-printscreen toggles between two
VCs and neither cntl-printscreen nor shift-printscreen seem to do
anything.  

However, shift-scroll lock, cntl-scroll lock, and right alt-scroll lock
dump some interesting things into /var/adm/messages.

Also, I don't find documentation anywhere in the kernel source tree
(i.e. searching for the strings "printscreen", "print screen", or
"scroll lock").
