Men ikke altid kan andre komponenter.
I foråret 1998 kunne Riva128 i nogle XFree86 udgaver ikke
tåle shared IRQ. (fejl i Xfree86)
Måske et problem med shared IRQ?

I sym53x8xx.c står følgende:

**  This driver also supports all the Symbios 53C8XX controller family, 
**  except 53C810 revisions < 16, 53C825 revisions < 16 and all 
**  revisions of 53C815 controllers.

Og i README.ncr53x8xx:

- ncr53c8xx generic driver that supports all the SYM53C8XX family including 
  the ealiest 810 rev. 1 and the latest 896 2 channels LVD SCSI controller.
- sym53c8xx enhanced driver (a.k.a. 896 drivers) that drops support of oldest 
  chips in order to gain advantage of new features, as LOAD/STORE intructions 
  available since the 810A and hardware phase mismatch available with the 
  latest 896.

Men måske der er sket ændringer siden kerne 2.2.13 hvorfra dette stammer...

Så bedst at checke med kernel-source.
