Waiter! Waiter! There is an 8051 in my 10Gbit Ethernet SFP+ module!

Don't worry about it too much, it's quite fault tolerant, all of the below worked at full speed just fine.

I wonder how much current I can draw from the 3.3V standby supply on the power button of my laptop...

How does that even happen?

Wanted to disable my rack cooling fans when the HDDs are spun down but I forgot about the toasty PSU that also needs cooling in there.

We already have people like that, and even though they could just google a question, they don't. And it's scary how little they know about survival, basic hygiene, food safety, politics, etc. We're already there.

Well jtag appears to be disabled, but I did find UART spitting out some numbers during startup. I guess the next step would be to look into the firmware and see what's that about.
