There is, assuming "boto" means boot...

Actually, nomodeset is it, AFAIK.  That turns of kernel-modesetting.  I 
believe a side effect would be turning off gallium as well, since AFAIK, 
gallium requires kernel modesetting (not userspace), but as you can likely 
deduce from the parameter itself, nomodeset as a kernel parameter tells 
the kernel not to modeset, therefore, no kms, ums (user-modesetting) 
instead.

Since unlike kms/ums, the difference between gallium and classic but kms 
drivers is entirely X config, that can be set after boot, from userspace, 
while kms cannot.  Presumably, you'd have xorg.conf.d (or xorg.conf if pre 
xorg-server-1.8 or if you prefer it) settings for both gallium and classic 
drivers, using only the single driver line in the device section to switch 
between them.  That could be done via sed in a script, if you want to be 
able to run either one, and that in turn controlled by a kernel commandline 
option if you wanted to set it at boot and then boot directly into X and a 
*dm instead of using the CLI login and startx, as I do here.
