The lm_sensors support for the via686a chip used on these Motherboard is not included in RH7.0. (kernel-2.2.16) Although identified by sensors-detect, the module via686a is missing. I use lm_sensors quite extensively on many machines, and newer machines come with the ASUS CUV4X Motherboard that requires that module. So this is a showstopper for me. Up to RH6.2 I used to build lm_sensors by myself, and it works more or less flawlessly with that Motherboard, so I know it should work.
The kernel is also missing the i2c-viapro and i2c-matrox drivers. Compiling them outside the kernel tree with the latest lm_sensors packages works fine with the RH7 dist. of the rest of lm_sensors.
ftp://ftp.redhat.com/pub/redhat/beta/fisher/en/OS/i386/RedHat/RPMS/lm_sensors-2.5.5-1.i386.rpm seems to be missing the Analog Devices ADM9240 driver as well (adm9240.o)
