I don't have a reference list ...... maybe if there is one someone will jump in.
Here are a few to begin with ...... maybe make a list?
livecd=* <path to *.sqfs file>
bootfromiso=* <path to *iso file>
changes_dev= <path to where the changes are located for persistence)
changes_file= <path to special changes file for persistence>
Here are the ones from the link you gave above for anyone interested ...
initrd <Only boot the initrd>
For LiveCD use
home=usb <Allows you to use the guest account to save and store settings.>
noeject <Disable the ejection of the CD on shutdown.>
noscsi <Disable the probing of SCSI devices at boot.>
nousb <Disable the probing of USB devices at boot.>
nopcmcia <Disable the probing of PCMCVIA devices at boot.>
nonetwork <Disable probing for network at boot.>
nosound <Disable probing for soundcard at boot.>
xdrv= <Specify the xdriver such as fbdev or nv>
xbpp= <Specify the bitdepth for X - can be one of 8, 15, 16, 24 or 32.>
xres= <Specify the resolution for X. - can be one of 800×600, 1024×768, 1280×1024 or 1600×1400.>
hwdetect=no <Don't run the hardware detection script.>
keyb= <valid keyboard map such as us,ie, de etc>
Is it something like the above you wanted to see?
I am sure there are lots more that can be added ...... if someone else would care to jump in with the info.
