	I'm positive that apm is power management. Its enabled in the
	2.2.16 kernel and seems to be running just fine. Under 2.4.0,
	i have:

		General Setup->
              <M>   Advanced Power Management BIOS support
		[*]     Ignore USER SUSPEND
		[*]     Enable PM at boot time
		[*]     Make CPU Idle calls when idle
		[*]     Enable console blanking using APM
		[*]     RTC stores time in GMT
		[*]     Allow interrupts during APM BIOS calls
		[*]     Use real mode APM BIOS call to power off

	Yes, i agree. However I am not certain how exactly to do so.
	I was hoping that there was a patch for the kernel that would
	include this support, but apparently not.

	i downloaded this from http://download.sourceforge.net/rio500/
	its the rio500-0.6.tar.gz file.
