Yes and No.
1. "pnp_reserve_irq=5" does not work because the module who accepts that
parameter is unknown. At least parport_pc does not understand that.
2. "options parport_pc io=0x278 irq=5" does not work.
3. This one, call it minimum adequate intervention in userspace, works:
"options parport_pc io=0x378,0x278 irq=7,5"

The observation with your two patches applied against 2.6.27-rc3 says that
without any BIOS reservation using the above options line is enough for the
kernel to know that parport 0 gets IRQ 7 and parport 1 gets IRQ 5.
This is what I would call progress. :)
The second advantage is that those annoying MPU 401 messages should be gone
now. :)
But: the sound card module is not loaded anymore, and I have seen some
checksum error, some hex address or similar.
Looks like that:
pnp 01:00: get resources
01:01: invalid checksum 0x59
01:01: card 'Analog Devices AD1816A'
isapnp: 1 Plug & Play card detected total
That also does not change if I free up IRQ 5 and / or 10 in my BIOS.
IRQ 10 would then appear in the system info as unused, but the sound card
module won't load.

No, not within the latest state of development.

If I were so easily to satisfy I would not spend that enormous amount of time
for finding solutions.... :)

Please see two attachments:
1. 2627rc3.txt
2. messages.txt: the complete log inheriting all dmesgs (because you mentioned
you would miss some info)
PS.: The only thing missing now is the plug and play driver passing IRQ 10 or
11 to the ISA PnP sound card WITHOUT BIOS changes.....
That's it what I would call the optimal compromise....
On the other hand: If I do need to force everything by BIOS changes or
additional kernel parameters then the PNP driver concept is worthless.
I understand that a Non-PnP ISA card needs some help at least by kernel
parameters, and if the same module touches a PNP device this PnP device must
be mentioned too in the kernel parameter statement, but the rest of the
ressources should be assigned automatically, shouldn't they?
Uwe
P. S. 2: Kernel 2.6.26 behaves totally different: it simply ignores the kernel
parameters and assigns IRQ 5 to the sound card, whatever happens.
You do not have any chance to assign an interrupt to rthe second parport, if
you do not change your BIOS values. To achieve that I do not need any PnP
architecture, do I?
options parport_pc io=0x378,0x278 irq=7,5
no BIOS reservations!
