I'm using kernel 2.6.9 from unstable, tried 2.6.8 also with exactly
the same problem. I don't explicitly load fb device. lsmod shows me
fbcon, font and vesafb modules loaded, which I can unload. greping
through /var/log/XFree86.0.log gives me this:
[EMAIL PROTECTED]:~$ egrep -i '(fb|framebuffer)' /var/log/XFree86.0.log
(**) TRIDENT(0): Depth 24, (--) framebuffer bpp 32
(**) TRIDENT(0): Option "ShadowFB" "false"
(==) TRIDENT(0): Linear framebuffer at 0x80800000
(II) Loading sub module "fb"
(II) LoadModule: "fb"
(II) Loading /usr/X11R6/lib/modules/libfb.a
(II) Module fb: vendor="The XFree86 Project"

in XFree86-4 I have following relevant sections:
Section "Module"
Load "GLcore"
Load "bitmap"
Load "dbe"
Load "ddc"
Load "dri"
Load "extmod"
Load "glx"
Load "record"
Load "speedo"
Load "type1"
Load "vbe"
Load "xtt"
EndSection
Section "Device"
Identifier "Trident Microsystems CyberBlade/i1"
Driver "trident"
Option "CyberShadow" "false"
Option "ShadowFB" "false"
Option "SWcursor" "false"
Option "PciRetry" "true"
Option "NoPciBurst" "true"
Option "NoAccel" "false"
EndSection
What does't it mean submodule? Does "trident" modules depend on fb?
