I have a 3.0GHz P4 HT in my laptop, with HT working fine(ish) on 2.6.13

I did some random grepping over my config file, and found these results:

# CONFIG_X86_BIGSMP is not set
CONFIG_SMP=y
CONFIG_X86_FIND_SMP_CONFIG=y
CONFIG_X86_SMP=y
CONFIG_ACPI_PROCESSOR=y
CONFIG_NR_CPUS=2

mine definately shows processor 0 and processor 1.  Also have a look
at /proc/acpi/processor/.  I have CPU0 and CPU1.

Is it a USB keyboard? did you enable usb legacy support in the bios?

don't know if you need this on.

while we're on bios settings, see if you can turn HT on and off in the
bios.  I have an option for it.

I don't know if any of this will help you, cause I don't know what your
problem is!  Hope something helps though.  Feel free to ask for more
info about my system.
