Exclamation Kernel recompiling woes (blank screen)

I recently upgraded my system from Slack 9.1 to 10.0, and ran into some startup errors relating to modules. There were a few things I wanted to change in my kernel anyway, so I thought I'd recompile.

I used what I am 99% sure was the .config file for the kernel Slack 10 installed and was currently running, and changed a couple of things not related to the display (actually, I think all of them were building some things into the kernel that were set to be built as modules). I recompiled, rebooted, and now I get a blank screen after LiLO does its thing. You can tell it's working in the background and Ctrl-Alt-Del will reboot fine, but I have no display. This happened a long time ago when I was trying to recompile, but I don't remember how (if?) I resolved it before, and can't figure out why it's doing that now.

Now I'm stuck on my old kernel which works, but none of the modules will load, I assume since they're built for the new kernel. Any ideas?

Sounds like a framebuffer problem. Make sure you have it enabled in your new kernel. Did you upgrade from an older kernel to a newer one? If so, your modules should still be there for the old kernel. Look in /lib/modules. Also, after you configured your new kernel, did you make the new modules for it; make modules && make modules_install. To fix the blank screen temporarily, you should be able to edit LILO's vga to normal; vga = normal. That might get you some text back up on the screen.

Ah right, that was the problem last time and this time. I'd turned off the "experimental options" setting so the framebuffer didn't show up as an option. Now I've run into another problem, though. Everything works fine on bootup, but if I startx and then Ctrl-Alt-F1 to get back to that tty, I just get flashing white pixels on a black screen (I can get back to X with Alt-F7, and I can type in the other terminals, just the display is messed up). I enabled both the framebuffer setting for my video card (ATI Radeon) and the default one (VGA or VESA, forget exactly what it was called). Do I need to change that and sit through another recompile again, or is something else causing this?
