with an unpatched legOS-2.3, there's no easy way to do that. The
incoming buffer is a static array inside function lnp_integrity_byte(),
it's not accessible from outside.
However, there is a hard way out (i used it during development of lnpd)
Write your own IRQ handlers for receiving and receive-errors -- you can
use the legOS-routines as a starting point -- and make the IRQ-Vectors
in RAM point to your routines. This way you can completely bypass LNP's
receive routines.
BTW, what kind of remote control are you talking about -- is it a
LEGO-part ?
Perhaps we should try to figure out what protocol this remote-control
uses and add some appropriate code to legOS.

the function is inlined, it's trivial -- from lnp.h:
//! set the integrity layer packet handler
extern inline void lnp_integrity_set_handler(lnp_integrity_handler_t
handler)
{
lnp_integrity_handler = handler;
}
