Not sure if I understood the problem correctly.
Are you looking for HVD or LVD?
The latter is no problem, there's plenty of LSI20320IE, which use the 
53c1020F and a PLX PCI-X<->PCIe bridge.
There's also a quiet well maintained Dell OEM firmware which added boot 
support improvement which I don't remeber all, but I'm running this 
firmware also on HP and original LSI cards (make sure to check the chip 
revision, there's a difference in 1030[""|"T"], while the latter is 
similar to 1020F – ATTENTION, please read yourself the correct numbers, 
just typing from memory, might not be exactly correct!
(all to IT firmware, IR is another sotry, I never had a 53c1030 with 
Raid Firmware in operation)

vhdci68->hd68 cables are no problem to get, so I guess it doesn't matter 
that the 20320IE has VHDCI as opposed to one card shown in your picters, 
which has HD68.
I also used the 20320 in SE mode. No problems besides implcit SE 
limitations.
If it's about HVD, I can't tell much.  I guess I have a RS/6000 with an 
HVD controller, but never found time to check/play.

You can look for firmware here: ftp://ftp.omnilan.depub/firmware/ 
[Dell|LSI].  Somtimes I x-linked compatible images, but not for the 
53c1030 as far as I could see.

Best,

P.S.: Has anybody used HPs Tape boot firmware feature?  Always wondered 
how they implemented this and if it really works with what drives on 
what hosts...
