APM minutes/seconds confusion

Hey guys,

	Before I start, I am no APM expert =)

	If I am correct, this applies to both DragonFly BSD and FreeBSD.
The problem is that most applications which call upon APM for battery
information such as time remaining assume it to always be in seconds.

However, in i386/apm/apm.c we see:

/* get power status per battery */
static int
apm_get_pwstatus(apm_pwstatus_t app)
{
	struct apm_softc *sc = &apm_softc;

	if (app->ap_device != PMDV_ALLDEV &&
	    (app->ap_device < PMDV_BATT0 || app->ap_device > PMDV_BATT_ALL))
		return 1;

	sc->bios.r.eax = (APM_BIOS << 8) | APM_GETPWSTATUS;
	sc->bios.r.ebx = app->ap_device;
	sc->bios.r.ecx = 0;
	sc->bios.r.edx = 0xffff;	/* default to unknown battery time */

	if (apm_bioscall())
		return 1;

	app->ap_acline    = (sc->bios.r.ebx >> 8) & 0xff;
	app->ap_batt_stat = sc->bios.r.ebx & 0xff;
	app->ap_batt_flag = (sc->bios.r.ecx >> 8) & 0xff;
	app->ap_batt_life = sc->bios.r.ecx & 0xff;
	sc->bios.r.edx &= 0xffff;
	if (sc->bios.r.edx == 0xffff)	/* Time is unknown */
		app->ap_batt_time = -1;

	<-LOOK HERE->
	else if (sc->bios.r.edx & 0x8000)	/* Time is in minutes */
		app->ap_batt_time = (sc->bios.r.edx & 0x7fff) * 60;
	<-LOOK HERE->
	else				/* Time is in seconds */
		app->ap_batt_time = sc->bios.r.edx;

	return 0;
}
