Nate,
First off, this is the big green laptop that has a desktop P4 in it, so I'm
aware that this is very much an edge case. The system does support ACPI duty
width type throttling and even has the T2 and T3 constants for use with _PSV.
I tried cpufreq(4) on it with the recent updates and it's not too happy.
Before the p4tcc driver was added, this is what I got:
CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz (2392.25-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0xf24 Stepping = 4
Features=0x3febf9ff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,SEP,MTRR,PGE,MCA,CMOV,P
AT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM>
...
cpu0: <ACPI CPU (3 Cx states)> on acpi0
acpi_throttle0: <ACPI CPU Throttling> on cpu0
acpi_perf0: <ACPI CPU Frequency Control> on cpu0
dev.cpu.0.%desc: ACPI CPU (3 Cx states)
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0
dev.cpu.0.freq: -1
dev.cpu.0.freq_levels: 9999/99999 9999/99999 8749/87499 7499/74999 6249/62499 4999/49999 3749/37499 2499/24999 1249/12499
After building a kernel from yesterday, I get this output:
CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz (2392.25-MHz 686-class CPU)

In addition, the newer kernel breaks Xorg, though that may not be cpufreq's problem:
Release Date: 18 December 2003
X Protocol Version 11, Revision 0, Release 6.7
