Here's my current kernel entry from /boot/grub/menu.lst:

title  GNU/Linux G550
root (hd0,0)
kernel /boot/bzImage.qx3 root=/dev/hda1 rw vga=normal 
video=matrox:vesa:443,sync:3,depth:32 hdc=ide-scsi

that last line is part of the previous line (kernel blah blah)

and then at boot time (or via dmesg) you should see something like this:
