holding down option key no longer works
I just upgraded recently to 10.9.1 from 10.8.5. I don't know if this has anything to do with my problem, but holding down the option key when restarting doesn't work at all. I get about 30 seconds of a grey screen, then a cursor appears, and nothing happens. I can wait forever and the drives that contain boot volumes do not show up. The only way I can boot off a different drive is to select the new location in System Prefs. This works when everything is fine, but I'm concerned that if anything happens to my boot drive, I'm hosed because I can't seem to get holding down the option key to work.

Also, assuming here you have a time-backup of your system somewhere? as anything boot related is a 'go carefully' area.
I am not a mac pro user (iMacs and mini's in the past for me) but seem to have found related information to your problem.
The SMC controller could need a reset.
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
Permissions might need to be fixed on the drive.

Thanks all for your suggestions. Unfortunately, none of them seemed to work.
However, through trial and error, I DID figure out that the presence of a PCIe Sonnet SSD card seems to be the culprit. When I removed the card, holding down option worked.

My Sonnet Pro card caused the boot-options to become unavailable ... but for some unknown reason they reappeared again after fooling around with configurations and PCIe card slot locations. Currently I do have boot-options with the Sonnet card installed. I also found that it was the presence of a bootable SSD on the card which caused the issue when I had the problems ... data SSDs were fine.
Resetting the PRAM caused my system to always boot to OS X, so when I was having the problem, that was my recovery method.
Good luck, and let us all know if you find a solution ...
