In those cases, the companies referring to "software executable ROM
updates" are really updating Flash RAM (or possibly an EEPROM?). They
just call it ROM so people don't confuse it with real useable RAM on a
machine.
AFAIK-
In the case of Palm system patches however, the patches live in RAM, and
override the syscall (trap). This is how they can update ROM based Palms
with system patches (or, in reality, provide the illusion that ROM has
been updated).
