Some more observation: while in /proc/interrupts the counter in line

1: 36989 IO-APIC-edge keyboard
is also increases by 2 as I press a key.

I agree. My feeling is that it is sometimes triggered simply by keyboard
or mouse use.

Yes, console or xdm. I haven't experienced the problem during ssh logins.

I have been using a PS2 mouse and (I think) a PS2 keyboard (it's an IBM
NetVista machine with its original mouse & keyboard). I'll try to get USB ones.

Do you mean to recompile a kernel with some options disabled ? If yes,
which of the following options should I disable:

CONFIG_X86_GOOD_APIC=y
CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y

CONFIG_APM=m
CONFIG_APM_RTC_IS_GMT=y

CONFIG_HOTPLUG_PCI_ACPI=m
CONFIG_ACPI=y
CONFIG_ACPI_blabla=y
?
(Btw, CONFIG_ACPI has been already disabled in my custom kernel which also
showed the problem.)

Thanks for your help.
Andras
