I updated source and built world and kernel today.  My machine won't complete 
a dump and reboot. I'll work on that, but the below text is from a successful 
boot, and I show where the panic occurred.  I don't build all modules, but I 
added mmc, mmcsd, and sdhci to the var in make.conf. When this all began, I 
had built the modules and loaded them by hand. There was no panic, so I added 
them to /boot/loader.conf and then it panic'ed. I've also made it panic by 
stopping the boot and hand-loading the three modules. I haven't built these 
into a kernel...

The next line would have been:

Probably supported by sdhci(4).

I don't know which of the two controllers supports Sony Memory Sticks, but I 
figured I'd get the drivers installed and try it.
