I found a working export of 106A5 microcode. One of the original sites I was searching (Microcode repo) updated their copy and it does import correctly now. Details:
106A5 Revision 1D (2018-05-11) - Supported CPU's:
Intel Core Processor Extreme Edition i7-965
Intel Core Processor i7-920, 940 106A5 03 Stopped 0x1B --- ---
Bloomfield Xeon Intel Xeon Processor W3520, W3530, W3540, W3550,
W3565, W3570, W3580
Intel Xeon Processor W5580, W5590
Intel Xeon Processor X5550, X5560, X5570
Interestingly, they also had another 206C2 microcode update, with revision 1F with a date of 2018-05-08. However this copy was not injectable to our BIOS. As calestrom already tested the 206C2-1E patch and it has meltdown/spectre bug fixed. This 1F patch may be unnecessary. nontheless, I will monitor for a fixed 1F patch for us.
