However, as said previously in this thread, input-kbd won't work with any
RC table that uses NEC extended (and there are several devices on the
current Kernels with those tables), since it only reads up to 16 bits.

ir-keytable works with all RC tables, if you use a kernel equal or upper to
2.6.36, due to the usage of the new ioctl's.

Is there a way to control the key repeat rate for a device
controlled by ir-kbd-i2c ?

It appears to be limited to a max of between 4 and 5 repeats/sec somewhere,
and I'd like to fix that.

It depends on what device do you have. Several I2C chips have the repeat
logic inside the I2C microcontroller PROM firmware. or at the remote
controller itself. So, there's nothing we can do to change it.

I have even one device here (I think it is a saa7134-based Kworld device) 
that doesn't send any repeat event at all for most keys (I think it only
sends repeat events for volume - Can't remember the specific details anymore -
too many devices!).

The devices that produce repeat events can be adjusted via the normal
input layer tools like kbdrate.

Unfortunately kbdrate affects all connected devices and I am not sure if
there is a utility allowing to set rate on individual devices. But here
is the main part: 

static int input_set_rate(int fd,
			  unsigned int delay, unsigned int period)
{
	unsigned int rep[2] = { delay, period };

	if (ioctl(fd, EVIOCSREP, rep) < 0) {
		perror("evdev ioctl");
		return -1;
	}
	return 0;
}

Okay, if that's still a global in this day and age,
then I suppose I'll just have to special-case it here in my copy.

The hardware itself is capable of much faster repeat rates,
and prior to 2.6.36 I used to patch it for intelligent ramp-up
on repeats inside ir-kbd-i2c.

As of 2.6.36 that stopped working, and is now limited somewhere
to no more than one repeat every 210msecs.
