Yes, I installed Fc5 with only two drives in a mirror.  Worked like a champ.
As I recall, I was installing from a Unity Respin.

I tried raid 0 and raid 1.  Only had two drives so I could not test raid 
0+1.  I ended up doing most of my tests on a single drive config with 
i686 on one drive and x86_64 on the other.

I ran a series of spec oriented and office use, desktop use, developer 
use, and database use benchmarks on the systems in both 32 and 64 bit mode.

I used kernel builds and gcc builds for the developer tests.

Although my employer would not like it if I published official results, 
I will say that this was a comparison of servers from HP, SUN, DELL, and 
white box.

After the testing I concluded:

The SUN box is a good purchase decision even though it is almost twice 
the cost of the white box we tested.  The construction and quality of 
the box is excellent, and performance is top notch.  The only downside 
was the NOISE! :)

Also, I was interested in performance of 64bit vs 32bit and found that 
the AMD Opeteron and X2 processors like 64bit better than 32bit.  Or 
rather, I liked the performance better.

The intel based Dell servers that I tested tested were just the 
opposite.  They preferred running in 32bit mode.

YMMV, of course.
