Solaris 10 installing on Cisco UCS doesn't see HBAs

The chassis config is right... this blade can boot to VMware ESXi and see HBAs and LUNs. Solaris isn't seeing the HBAs at all... luxadm probe returns ERROR: No Fibre Channel Adapters found.
fcinfo hba-port -l returns No Adapters Found.

prtdiag -v gets me:

==== Upgradeable Slots ==============================

I cannot find a download for drivers for UCS and Solaris, or I'd be figuring I need to stand up a jumpstart server or otherwise customize the install process. Googling turns up some old posts that seem to suggest that Solaris can be installed on this hardware. So I could use a pointer!

What's the output from running scanpci?

It does show two entries like:

pci bus 0x000a cardnum 0x00 function 0x00: vendor 0x1137 device 0x0045
 Cisco Systems Inc VIC FCoE HBA

looks like an HBA driver issue, I would suggest an SR is in order.
