X will not start if press ESC at boot process

[Wheelz]

Hi,

My boot parameter is "rhgb vga=0x318 quiet", my video card is NVIDIA
Quadro NVS 140M(using driver from rpmfusion, akmod-nvidia), 
system is fedora 10 rawhide updated to Oct. 18,

During the boot process, after the "fedora" flash showed up, just wait 
two or three seconds, then press ESC, the X will not start up.
if I don't press ESC during the boot, the X can start normally.


And another strange thing, if I disable NVIDIA driver(by uninstall rpms), 
and use the nv driver. whatever I input by keyboard will also be given to
the system console, including the password I entered in gdm. If I press 
Ctrl+C in a gnome terminal，the X will restart.
