Applied this patch, made sure I had compiled in hpsa and not cciss to 
avoid any variables from initramfs, and still I get this:

[    4.015080] hpsa 0000:00:04.0: unrecognized board ID: 0x40800e11, ignoring.
[    4.098473] hpsa 0000:00:04.0: Board ID not found

Boot command line was "root=/dev/sda1 console=ttyS0,9600 ro hpsa_allow_any=1" - 
seems correct.

By looking at the code, I should see "unsupported board ID:" and it 
should work, but I see "unrecognized board ID:" and it does not work.

Hmm, trying hpsa.hpsa_allow_any=1. Much better:

Controller is detected, there is something behind it but no sda is 
detected and no bootup.

What next?

And, for readability, we should use something like "Using unsupported 
board ID", not plain "unsupported board ID" - the last one leaves 
assumption that it will not work, although it should.
