Currently Linux operating systems have not been tested on this board according to this link: http://support.intel.com/support/motherboards/desktop/sb/CS-008326.htm
I guess there should be some reason why Intel has not validated Linux operating system for this board (or chipset).
However I would recommend you to check with Red Hat for any compatibility issues with this board or even with this specific chipset G33. There could be some changes in the kernel of the operating system that is not supported by this chipset compared to the other Linux OSes.
Hope this will be helpful.
