Noted. ;) But then I also use another script to drive the make and install, with everything in it having an ' && \' at the end of the lines so any error bails out right there leaving the message still on-screen
Its a bit longer as I've hacked around to ensure continuity over the years of the firmware trees etc. I can post that too if anyone wants it.

I use the scripts, which of course are subject to internal revision if it proves I am not doing it right, as a way to get absolute consistency. For the makeit script, it has only one var, $VER, assigned at the top to be the 2.6.whatever its building. All I have to do if it runs to completion is construct a new entry in /boot/grub/menu.lst. change the default and reboot.
Otherwise I'd forget (senor moment ;) some step in the middle and wind up needing more naproxin sodium to quell the headache I got from beating it on the wall....

Ken may have a point, next time I reboot, I'll drag out an install cd and run the memtest from it for at least 1 full cycle.
Another item I might add is that I have now tried several different number formats for the kernel command line option vga=, trying std octal, std 0xhex, and plain decimal, but it always hangs like I'd entered vga=ask. The boot continues normally in the selected 1680x1050x32 screen if I enter either a 'z' or a '369' at that point. So something seems to be preventing the vga= from working correctly as a command line argument. Who knows, maybe there is a bad address line on one of the 4 sticks again and it hits that exact address at each boot. Murphy again, darn him.
