Any idea whether the internal Gigabit Ethernet ports support speed autonegotation?

Don't believe so , believe they are all gig speed internally . The uplinks are configurable.

1-16 are not speed configurable even if the commands are there , right out of the iegsm config guide.
Switch ports 1 to 14 are internal 1000 Mbps connections to the other blades in the BladeCenter.
These ports operate at 1000 Mbps in full-duplex mode.
Switch ports 15 and 16 are internal 100 Mbps connections to the Management Module. These ports
operate at 100 Mbps in full-duplex mode.
Note You cannot change the speed and duplex settings on the internal ports 1 to 16.
Switch ports 17 to 20 are for connections to external devices such as other switches. Depending on
the switch model, you can change the speed and duplex settings on the external ports 17 to 20.

dude, i have both the p/c class hp blade switches and i can either setup the speed/duplex to auto or static without any issues. Most of my servers are using speed auto.

Dude then either you or cisco's docs are incorrect...

dont always believe what you see on the cisco docs. you have to try it yourself.
if you want i can send you print screen as a proof.
