First-thanks for your reply.
1)When i boot with stock kernel 2.6.22-3-alpha-smp ,i go ->into X-session
(gnome-session,  gdm is installed) .

Hmm, but before starting X, does it use a framebuffer driver or text mode? You may need to look closely, or maybe look at dmesg. You could also press Ctrl-Alt-F1 to go back to a normal console.

2)My video card is 'glint' driver(pm2 card).driver in/etc/X11/ xorg.conf is
3)I am not using 'fbdev' as driver in xorg.conf
4)In kernel .config file i have all the graphics options enabled that i
normally would need.

Does that include CONFIG_FB_PM2?

5) there is no /dev/fb0, #ls -l /dev/fb0 -> /dev/null on my box?

Not existing is different from a symlink to /dev/null. Anyways, does it not exist with either kernel?

Are you using the UseFBDev option in xorg.conf?

Have you very carefully looked through /var/log/Xorg.0.log and compared it to what you get when it does work?

linux-2.26.23-12 kernel builds fine and boots but xinit fails with 'No
/dev/fb0' support, this of course is xorg. All graphics/ fbdev kernel
options are turned on.
Any help here would be appreciated.

Forgive me for asking the obvious questions, but:

What graphics card do you have?

Why does xinit care about /dev/fb0? Are you using the framebuffer driver
in xorg? If so, why aren't you using the driver for your video card? Are
you using the option that tries to do framebuffer magic when switching

Is one of the kernel's framebuffer drivers getting used? IE, is your
console in text mode or graphics mode? Which framebuffer driver was
getting used with the previous kernel?

Does /dev/fb0 exist? Are you running udev?

From the little you said, my best guess would be that you are using the
fbdev xorg driver, and aren't getting the kernel framebuffer initalized
for some reason.
