Feature request - startup menu option

I have a particularly odd set of hardware, that I figure some other folks might have to contend with:

1) My hard drive (CF Microdrive) does not support DMA.
2) I have only USB ports, that do not support PS2 emulation of the keyboard in BIOS

A combination of the boot menu options works, but I had to do them by
hand on the command line, and then modify the kernel parameters such
that they stuck after pfSense was installed.  i.e. disable dma,
enable usb keyboard.

This was with 1.0beta2, beta3 seems to have installed fine, but I haven't checked the DMA issue with it.
