ACPI problems with kernel 2.6.x for Dell Inspiron 4100



For kernels 2.4.x ACPI is automatically disabled:
ACPI: Subsystem revision 20040326
ACPI: Interpreter disabled.

while kernels 2.6.x enables it:
ACPI: Subsystem revision 20040816
ACPI: Interpreter enabled
ACPI: Using PIC for interrupt routing
ACPI: PCI Root Bridge [PCI0] (00:00)
PCI: Probing PCI hardware (bus 00)
PCI: Ignoring BAR0-3 of IDE controller 0000:00:1f.1
PCI: Transparent bridge - 0000:00:1e.0
ACPI: PCI Interrupt Routing Table [\_SB_.PCI0._PRT]
ACPI: PCI Interrupt Link [LNKA] (IRQs 9 10 *11)
ACPI: PCI Interrupt Link [LNKB] (IRQs 5 7) *11
ACPI: PCI Interrupt Link [LNKC] (IRQs 9 10 *11)
ACPI: PCI Interrupt Link [LNKD] (IRQs 5 7 9 10 *11)
ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.AGP_._PRT]
ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PCIE._PRT]
ACPI: Power Resource [PADA] (on)
PCI: Using ACPI for IRQ routing
ACPI: PCI Interrupt Link [LNKA] enabled at IRQ 11
ACPI: PCI interrupt 0000:00:1d.0[A] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI interrupt 0000:00:1f.1[A] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 7
ACPI: PCI interrupt 0000:00:1f.5[B] -> GSI 7 (level, low) -> IRQ 7
ACPI: PCI interrupt 0000:00:1f.6[B] -> GSI 7 (level, low) -> IRQ 7
ACPI: PCI interrupt 0000:01:00.0[A] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI Interrupt Link [LNKC] enabled at IRQ 11
ACPI: PCI interrupt 0000:02:00.0[A] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI Interrupt Link [LNKD] enabled at IRQ 11
ACPI: PCI interrupt 0000:02:01.0[A] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI interrupt 0000:02:01.1[A] -> GSI 11 (level, low) -> IRQ 11
ACPI: PCI interrupt 0000:00:1f.6[B] -> GSI 7 (level, low) -> IRQ 7
ACPI: (supports S0 S1 S3 S4 S4bios S5)
ACPI wakeup devices:
 LID PBTN PCI0 UAR1 USB0 USB1 USB2 MODM PCIE MPCI
...
Alocation of IRQ 7 does not seem to work: (this IRQ is allocated by
parport0)
ACPI: PCI interrupt 0000:00:1f.5[B] -> GSI 7 (level, low) -> IRQ 7
unable to grab IRQ 7
Intel ICH: probe of 0000:00:1f.5 failed with error -16
and apm is shut off:
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac)
apm: overridden by ACPI.
apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac)
apm: disabled on user request.
================================
The main problem is that alsa does not work, neither does the battery
monitor in gnome, the only option is to boot with acpi=off. 

For alsa the audio device is not found:
Running alsaconf or (/etc/init.d/alsa start when configured):
ACPI: PCI interrupt 0000:00:1f.5[B] -> GSI 7 (level, low) -> IRQ 7

/etc/init.d/alsa stop

Loading driver...
Starting ALSA.../etc/init.d/alsa: Error: alsactl restore failed with
message 'alsactl: load_state:1134: No soundcards found...'.
done.

The battery monitor shows the following problem:
Can't access ACPI events in /var/run/acpid.socket!
Make sure the ACPI subsystem is working and acpid daemon is running.

Is the ACPI support not functional for this Dell laptop? Can I upgrade
the BIOS?
