| 
| No, you probably don't need it.  Depends on your apps/usage,

| | Not that I can find, and I'm restricted to a make menuconfig, xconfig 
| | is broken because its not seeing the correct libqt-mt library.  Its 
| | complaining about the version in kde3.2.3, but all the env stuff now

| 
| Dunno, I've seen some similar problems.
|

|

Well, I managed to whack an ext3 partition (/) and have to reinstall it.

Just from looking at your .config, I suggest turning off some/all/most
of these to see if it will boot and run for awhile:

CONFIG_HPET_TIMER=y
CONFIG_HPET_EMULATE_RTC=y

CONFIG_PREEMPT=y
CONFIG_INPUT_EVBUG=y

CONFIG_IPMI_HANDLER=y
CONFIG_IPMI_DEVICE_INTERFACE=y

CONFIG_4KSTACKS=y
