I am positive that when I don't press escape that GRUB is defaulting to the most recent kernel, as I have removed all old kernels from my system and currently have only one installed.

I have GRUB 2 installed, which no longer has a menu.lst file. I manually removed the "quiet" and added the "nosplash" boot options from/to the GRUB command line. This did not resolve the problem.

I still wonder if this problem could be related to kernel mode setting in the Intel driver. I believe the Linux kernel framebuffer is used to show some of the splash screens prior to X.Org start; and the framebuffer has its own driver(s), but I don't know if they share any code with parts of the Intel driver in the kernel.

I used to occasionally have the same problem when switching between virtual terminals; however, I just tried to replicate that problem, and I can't seem to make this happen, at least at the moment. (In fact, this is what originally made me suspect it was a mode setting problem--I believe that not only is mode setting normally done when booting but also when switching between GUI and virtual terminal.)

For purposes of disclosure, I am affected by the following bug; and I don't know if this is related:

In addition, I see several instances of the following messages in dmesg; and I don't know if they are related:
"i2c-adapter i2c-1: unable to read EDID block."
"i915 0000:00:02.0: LVDS-1: no EDID data"
