Hi,

I got a Dell Precision M70. All the ACPI features (battery, power 
buttons, change CPU frequency, temperature) seam to work, except the 
suspend modes. Here is what I get:

acpi0: <DELL CPi R  > on motherboard
acpi_timer0: <24-bit timer at 3.579545MHz> port 0x1008-0x100b on acpi0
cpu0: <ACPI CPU (4 Cx states)> on acpi0
acpi_throttle0: <ACPI CPU Throttling> on cpu0
acpi_acad0: <AC Adapter> on acpi0
acpi_cmbat0: <Control Method Battery> on acpi0
acpi_cmbat1: <Control Method Battery> on acpi0
acpi_lid0: <Control Method Lid Switch> on acpi0
acpi_button0: <Power Button> on acpi0
acpi_button1: <Sleep Button> on acpi0
pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0
acpi_tz0: <Thermal Zone> on acpi0
atkbdc0: <Keyboard controller (i8042)> port 0x66,0x62,0x64,0x60 irq 1 on 
acpi0
sio0: <16550A-compatible COM port> port 0x3f8-0x3ff irq 4 flags 0x10 on 
acpi0

Jun  3 11:44:19 mdaemon acpi: resumed at 20050603 11:44:19

How can I fix it?

Thanks!
