[CentOS] RAID support in kernel?

I'm setting up a computer that will run 'CentOS 6 server'. The MB is an 
Asus with a hw raid controller (Promise PDC-20276), which I want to use 
in RAID-1 mode. I noted (from a MB website) that it also needs a driver 
- which is probably why it's called a 'fakeraid'.

So, I've been trying to determine if any recent kernels support this 
chip. Using google.com/linux, I found lots of hits dating about 2002 - 
04, and referencing the 2.4 kernel (which had the driver compiled into 
it). But, nothing newer.

I checked kernel.org and kernelnewbies.org - I see that raid-1 is 
supported. But, I can't find any reference to this chip.

How can I find out what drivers are compiled into a given kernel? Or, 
basically what hardware a given kernel supports?
