The only thing that seems odd is sys time taking 99% of cpu when
starting spamd (spamassassin) from pkgsrc, which took nearly a
minute to start...

  99.1% Sy   0.9% Us   0.0% Ni   0.0% In   0.0% Id    pages

could this have something to do with acpi speedstep (this is rc1)?
how can I check the actual clock rate the system is running at?

this (from top) is also odd...

   16 root      18    0     0K 9488K syncer    51:18  3.91%  3.91% [ioflush]

that process seems to be keeping the load above .8; there are no
io problems in dmesg...  Oh,

viaide0 at pci0 dev 6 function 0
viaide0: NVIDIA nForce4 IDE Controller (rev. 0xf2)
viaide0: bus-master DMA support present
viaide0: primary channel configured to compatibility mode
viaide0: primary channel interrupting at ioapic0 pin 14 (irq 14)
atabus0 at viaide0 channel 0
viaide0: secondary channel configured to compatibility mode
viaide0: secondary channel interrupting at ioapic0 pin 15 (irq 15)

wd0 at atabus2 drive 0: <ST380013AS>
wd0: drive supports 16-sector PIO transfers, LBA48 addressing
wd0: 76319 MB, 155061 cyl, 16 head, 63 sec, 512 bytes/sect x 156301488 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133)
wd0(viaide1:0:0): using PIO mode 4, Ultra-DMA mode 6 (Ultra/133) (using DMA)

I thought since I had Ultra/133, I was okay. Is "compatibility
mode" my problem? Do I need sata controler to fix?
