OK, there are two situations at work here.

1. at startup the framebuffer resolutions are controlled by extra
kernel parameters 'VGA=hexcode' (google for these). The frequency
(correct me if I am wrong) does not come into play here.

Sample grub kernel line
kernel  /boot/<kernelname> root=<root partition> ro quiet vga=791

2. The resolutions and the frequencies for X are controlled by xorg.conf
