One thing recent kernels started to do is to wait for an actual monitor 
connection to adjust actual screen resolution rather than using some 
defaults.

What you might still do is to tell the kernel what screen resolution to 
assume so the video driver won't wait for a real monitor. For example, 
you could add the following to your kernel cmdline:

	vga=775 video=1280x1024 at 60e

Indeed. And I presume that gdm didn't start listening for keyboard 
events yet if it is waiting for a monitor. This could be worthy of a bug 
report.
