forse ho capito cos'è che non va ...

lanciando "modprobe agpgart" mi restituisce il seguente output:
codice:
/lib/modules/2.4.29/kernel/drivers/char/agp/agpgart.o.gz: init_module: Invalid argument
/lib/modules/2.4.29/kernel/drivers/char/agp/agpgart.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
/lib/modules/2.4.29/kernel/drivers/char/agp/agpgart.o.gz: insmod /lib/modules/2.4.29/kernel/drivers/char/agp/agpgart.o.gz failed
/lib/modules/2.4.29/kernel/drivers/char/agp/agpgart.o.gz: insmod agpgart failed
e questo è dmesg:
codice:
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Detected Via Apollo Pro KT400 chipset
agpgart: unable to determine aperture size.
chi può dirmi come risolvere?
