Can't refuse to suspend

I don't know if my previous note made it onto this list or not.
(Actually, I'm not sure if this list is even working.)  I'm going to
proceed on the assumption that my previous note didn't get through, and
start back at ground zero.

I'm setting up Red Hat 6.0 on an IBM ThinkPad 770Z.  I've got just about
everything working, but I've found that a suspend/resume leaves the
sound drivers out of sync.  Unloading and reloading the sound driver
modules seems to correct the problem, and I want to use apmd_proxy to
do this--pretty straightforward so far.

The problem is that an open multimedia application will prevent the
sound drivers from unloading.  Therefore, I want apmd_proxy to refuse to
suspend when the drivers don't unload.  So far, however, I can't get the
system to not suspend, no matter what apmd_proxy returns.  (I have
verified that apmd_proxy is being executed.)

Is a certain kernel level required to get this to work?  I'm using apmd
3.0beta8 with kernel 2.2.10.  Here's the APM portion of my kernel
configuration:

     CONFIG_APM=y
     # CONFIG_APM_IGNORE_USER_SUSPEND is not set
     CONFIG_APM_DO_ENABLE=y
     CONFIG_APM_CPU_IDLE=y
     # CONFIG_APM_DISPLAY_BLANK is not set
     CONFIG_APM_POWER_OFF=y
     CONFIG_APM_IGNORE_MULTIPLE_SUSPEND=y
     CONFIG_APM_IGNORE_SUSPEND_BOUNCE=y
     # CONFIG_APM_RTC_IS_GMT is not set
     CONFIG_APM_ALLOW_INTS=y

Thanks!
