Same here: 
CPU: Intel(R) Core(TM)2 Duo CPU     T5870  @ 2.00GHz (1995.01-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0x6fd  Stepping = 13
  Features=0xbfebfbff<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,HTT,TM,PBE>
  Features2=0xe39d<SSE3,RSVD2,MON,DS_CPL,EST,TM2,SSSE3,CX16,xTPR,PDCM>
  AMD Features=0x20100000<NX,LM>

I don't have this card any more. And regarging my SD... I can't do exact measures.

What I have done yesterday is:

; Running at full frequency:
Oct 16 11:53:50 kibab-nb sudo: kibab : TTY=ttyp3 ; PWD=/home/kibab ; USER=root ; COMMAND=/etc/rc.d/powerd stop Oct 16 11:54:00 kibab-nb sudo: kibab : TTY=ttyp3 ; PWD=/home/kibab ; USER=root ; COMMAND=/usr/sbin/powerd -a max 
Oct 16 11:54:49 kibab-nb kernel: mmc0: <MMC/SD bus> on sdhci
0 Oct 16 11:54:49 kibab-nb kernel: mmc_send_app_ocond(): cmd completed in 0 iter 
Oct 16 11:54:50 kibab-nb kernel: mmc_send_app_ocond(): cmd completed in 35 iter

35 iterations!

; Running at lowest possible frequency:
Oct 16 11:55:27 kibab-nb sudo: kibab : TTY=ttyp3 ; PWD=/home/kibab ; USER=root ; COMMAND=/etc/rc.d/powerd stop Oct 16 11:55:30 kibab-nb sudo: kibab : TTY=ttyp3 ; PWD=/home/kibab ; USER=root ; COMMAND=/usr/sbin/powerd -a min 
Oct 16 11:55:46 kibab-nb kernel: mmc0: <MMC/SD bus> on sdhci0 
Oct 16 11:55:46 kibab-nb kernel: mmc_send_app_ocond(): cmd completed in 0 iter 
Oct 16 11:55:46 kibab-nb kernel: mmc_send_app_ocond(): cmd completed in 185 iter 

185 iterations at lowest frequency...

Sorry for long answer delay.
