It works ! I can access my CD-RW/DVD player and the HD without
disabling DMA in the BIOS.

I've put up the dmesg on http://www.weirdnet.nl/netbsd/sis.dmesg but
these are (what I think) the relevant parts :

pciide0 at pci0 dev 2 function 5: Silicon Integrated System 96X UDMA6 IDE controller (rev. 0x00)
pciide0: bus-master DMA support present
pciide0: primary channel wired to compatibility mode
wd0 at pciide0 channel 0 drive 0: <IC25N040ATCS04-0>
wd0: drive supports 16-sector PIO transfers, LBA addressing
wd0: 38154 MB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 78140160 sectors
wd0: 32-bit data port
wd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
pciide0: primary channel interrupting at irq 14
wd0(pciide0:0:0): using PIO mode 4, Ultra-DMA mode 5 (Ultra/100) (using DMA data transfers)
pciide0: secondary channel wired to compatibility mode
atapibus0 at pciide0 channel 1: 2 targets
cd0 at atapibus0 drive 0: <QSI CD-RW/DVD-ROM SBW-241, , VF10> cdrom removable
cd0: 32-bit data port
cd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 2 (Ultra/33)
pciide0: secondary channel interrupting at irq 15
cd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA data transfers)

Thanks Manuel !
