Use the arrow keys to select the kernel image you want to start, then hit 
"e" for edit and you jump to a screen typically with two or three lines of 
info (for root fs, kernel and initrd), select the kernel line and hit "e" 
again to edit the line, add the option "single" (or "1" I guess, although 
I've never used that) to the list of boot parameters. Then just hit "b" to 
boot the modified config. This is perhaps more cumbersome than Lilo, but it 
has the distinct advantage that if, in a moment of weakness, you stuck a 
bad boot param into your grub.conf file (I seem to remember having told 
Lilo to append mem=2014m in once when I actually meant 1024...),  you can 
edit it out using the same method.

Aside to the original poster: The "reboot" part is quite correct, but I'm 
not sure if anyone bothered to mention that it's generally possible to do a 
clean reboot (i.e. a proper shutdown and restart through software) without 
the root password. If you're starting a GUI automatically you can typically 
reboot the machine from one of the menu options presented at the logon 
screen. In text mode if you simply hit CTRL+ALT+DEL it will usually be 
intercepted by the OS and execute the command "shutdown -r now" (i.e. 
perform a reboot through software). This will avoid any potential 
filesystem corruption.

p.s. I am currently trying out a new version of Eudora (mail user agent for 
Windows) which hasn't downloaded it's registration key yet and thinks it's 
operating as advertising supported software. I apologize if it tacked some 
kind of add onto this message.
