SubjectFwd: ACPI & I4L irq confilct: bug reporting on kernel 2.4.0-test8-pre4

after further testing the problem seems to be in IRQ SHARING.
in fact, with acpi disabled, once the hisax has got irq 9 (it is not possible
for card type 36 to change the irq), i can load the ethernet modules
8390 and ne2k-pci for my ethernet PCI NE2000 card, but the ne2k-pci
driver also set its irq=9, so everytime i try to do:

ifconfig eth0 up

i get:

SIOCSIFFLAGS: resource temporarily unavailable

why don't add the irq parameter to the hisax winbond driver and to the
ne2k-pci driver ?

p.s.
my motherboard has pci slot 4 and slot 5 condivided and the isdn card is
on slot 4 while ethernet on slot 5.... so one may say "change your
motherboard", but everything worked fine with previous kernels (ACPI, Hisax,
ethernet)....

Please help me.
Many thanx.
