Description of problem:

I've just noticed the vbetool crashes with coredump on this command line:

'vbetool dpms'

(i.e.  on/off is missing option in this case)
Obviously  there is missing check before accessing (strcmp(argv[2], "on")
that argc is high enough for this.

#0  0x000000000040202e in main (argc=2, argv=0x7fffd70fa1a8) at vbetool.c:113
113			if (!strcmp(argv[2], "on")) {


Version-Release number of selected component (if applicable):
vbetool-1.2.2-1.fc12.x86_64

How reproducible:


Steps to Reproduce:
1. vbetool dpms
2.
3.
  
Actual results:


Expected results:
Error message/error code - just not coredump....
