ACPI Issues

I've been running current on my Sony FXA36 laptop for a couple months
now--works great, with a few minor acpi issues.
I have dumped my acpi code, and fixed up all compile problems, fwiw.
1) question/issue:
hw.acpi.supported_sleep_state: S3 S4 S5
yet lid_switch_state, standby_state, and sleep_button_state are all set
to S1--an unsupported mode. Would it make sense to determine what acpi
sleeps modes are supported at boot time, and then set these sysctl
values to something supported?
2) problem
when going to sleep mode (that is, S3 mode)--it powers down ok, and
revives ok on a keypress--but the screen only flashes on for one brief
second and then is off again. I can login to a prompt, type shutdown,
etc (without seeing the screen) and that works, so it's just the screen
that doesn't reinitialize--any way to get around this?
3) I'm assuming error messages like this one are simply a problem with
my laptop's acpi code and can't be avoided:
for instance, when I run the command
"acpiconf -i 0"
I get the following output
Jan 23 00:47:43 mycomp kernel: ACPI-0440: *** Error: Handler for
[EmbeddedControl] returned AE_NO_HARDWARE_RESPONSE
Jan 23 00:47:43 mycomp kernel: ACPI-1287: *** Error: Method execution

AE_NO_HARDWARE_RESPONSE

Jan 23 00:47:43 mycomp kernel: ACPI-1287: *** Error: Method execution

and at boot time, right the harvesting entropy line, and before the
swapon line, I get:
ACPI-0440: *** Error: Handler for [EmbeddedControl] returned
AE_NO_HARDWARE_RESPONSE
ACPI-1287: *** Error: Method execution failed

ACPI-1287: *** Error: Method execution failed [\_SB_.BAT1._BIF]
(Node 0xc2b6a780), AE_NO_HARDWARE_RESPONSE
(which I actually think is slightly different than I got before I
"fixed" my dsdt)
If there's anything to fix, I'll post dmesgs, the acpi code, etc if
anyone is interested.
thanks much,
Scott
