packages/modutils/modutils-collateral.bb: Modprobe has changed between 2.4 and 2.6 kernels. (sync with OE)
The information in /etc/modutils and /etc/modules.conf is not read under 2.6.
2.6 uses a /etc/modprobe.d directory, and it does not need a
"/etc/modprobe.conf" file; it reads all the appropriate *.conf files and
compiles the information at boot time.
This commit closes bug #808
