I was able to install Debian Wheezy on this hardware.
First, I had to hack the driver code to make it compile and copied the file into USB drive. During boot - I used netboot - the system did not recognize RAID array. Removed the kernel module from the memory, as newly compiled module has the same name. For some reason installer could not read the module from the USB drive, so I loaded it manually. Mounted USB drive and ran the insmod command pointing to the mounted file. Then I removed USB drive and repeated the step when installer re-scans the system. This time RAID was detected and installation succeeded. After reboot I installed backported kernel which has the newer driver version that detects RAID array without any problems.

The changes I made to the driver source are below:

diff --git a/drivers/scsi/hpsa.c b/drivers/scsi/hpsa.c

Hope that helps,
