It looks just like my hyperthreaded unit. I thought I had to turn on hyperthreading from the BIOS. Hyperthreading works very slick under a smp kernel for any compile type use. When creating a mp3 through lame single processor kernel would run at 1-2x playback speed and under hyperthreading the speed increased to 10-12x playback speed.

I was doing puttering around in winxp and noticed that that the device manager shows two processors. so i flipped into bios and there is now a setting to enable hyperthreading as well as the P4 w/ HT logo on the splash screen. in linux /proc/cpuinfo shows the following: # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Mobile Intel(R) Pentium(R) 4 CPU 3.06GHz stepping : 9 cpu MHz : 3056.542 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 6094.84 also, /proc/acpi/processor/ now has a CPU1 directory in addition to CPU0. does this mean Dell slipped me a newer unit with HT?
