I have compiled kernel 2.6.35 but there is huge difference in size
between 2.6.35.6-45.fc14.i686 (fedora core 14 ) and compiled one
I am using same configuration file as fc14 uses
following details show difference in size
[Anil@localhost linux-2.6.35]$ du -h
/lib/modules/2.6.35.6-45.fc14.i686/kernel/drivers/video/backlight/lcd.ko
8.0K /lib/modules/2.6.35.6-45.fc14.i686/kernel/drivers/video/backlight/lcd.ko
[Anil@localhost linux-2.6.35]$ du -h
/lib/modules/2.6.35/kernel/drivers/video/backlight/lcd.ko
160K /lib/modules/2.6.35/kernel/drivers/video/backlight/lcd.ko
[Anil@localhost linux-2.6.35]$
62M /lib/modules/2.6.35.6-45.fc14.i686/
587M /lib/modules/2.6.35/

Usually when this happens to me it is because debugging symbols are included
in the build. Are you sure the configuration file has them disabled? On Ubuntu,
for instance, the configuration file which is described as the same used by
kernel packagers actually has debugging enabled.
