HP/Compaq nx6325 clock "jumping around"

[Joerg Wunsch]

On a nx6325 running 6-stable (because I couldn't get 7.x to work with
ACPI at all so far), the main clock is frequently "jumping", up to a
level where ntpd eventually gives up:

Jul  2 10:44:44 remi ntpd[50885]: time reset +11.885037 s
Jul  2 10:44:44 remi ntpd[50885]: kernel time sync disabled 6041
Jul  2 10:54:24 remi ntpd[50885]: kernel time sync disabled 2041
Jul  2 11:07:13 remi ntpd[50885]: kernel time sync enabled 2001
Jul  2 11:45:44 remi ntpd[50885]: time reset +1.874996 s
Jul  2 11:45:44 remi ntpd[50885]: kernel time sync enabled 6001
Jul  2 11:55:25 remi ntpd[50885]: kernel time sync enabled 2001
Jul  2 12:06:07 remi ntpd[50885]: time reset -0.539515 s
Jul  2 13:47:45 remi ntpd[50885]: time reset +901.759394 s
Jul  2 13:47:45 remi ntpd[50885]: kernel time sync enabled 6001
Jul  2 13:57:25 remi ntpd[50885]: kernel time sync enabled 2001
Jul  2 14:05:58 remi ntpd[50885]: time reset +0.159707 s
Jul  2 14:24:08 remi ntpd[50885]: time reset +0.451464 s
Jul  2 14:42:15 remi ntpd[50885]: time reset +0.323177 s
Jul  2 15:00:25 remi ntpd[50885]: time reset -0.525669 s
Jul  2 15:45:34 remi ntpd[50885]: time reset -0.197339 s
Jul  2 18:10:59 remi ntpd[50885]: time reset +894.125104 s
Jul  2 18:10:59 remi ntpd[50885]: kernel time sync enabled 6001
Jul  2 19:03:17 remi ntpd[50885]: time correction of 1785 seconds exceeds sanity limit (1000); set clock manually to the correct UTC time.

Notice the huge time resets of about 900 seconds between.  Could this
be related to CPU frequency changes caused by whomever might control
that (ACPI BIOS?  powerd is not running, should I?)?  The CPU
frequencies listed are:

dev.cpu.0.freq: 1393
dev.cpu.0.freq_levels: 1990/100000 1791/81822 1592/65808 1393/57582 1194/49356 995/41130 796/22152 696/19383 597/16614 497/13845 398/11076 298/8307 199/5538 99/2769
