aesni module with AMD CPUs?

[Gót András]

Hi,

This is from a Linux machine:

processor	: 15
vendor_id	: AuthenticAMD
cpu family	: 21
model		: 1
model name	: AMD Opteron(tm) Processor 4280
stepping	: 2
microcode	: 0x6000624
cpu MHz		: 2800.277
cache size	: 2048 KB
physical id	: 1
siblings	: 8
core id		: 7
cpu cores	: 4
apicid		: 39
initial apicid	: 23
fpu		: yes
fpu_exception	: yes
cpuid level	: 13
wp		: yes
flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov 
pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt 
pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc extd_apicid 
aperfmperf pni pclmulqdq monitor ssse3 cx16 sse4_1 sse4_2 popcnt aes 
xsave avx lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a 
misalignsse 3dnowprefetch osvw ibs xop skinit wdt lwp fma4 nodeid_msr 
topoext perfctr_core arat cpb npt lbrv svm_lock nrip_save tsc_scale 
vmcb_clean flushbyasid decodeassists pausefilter pfthreshold

AFAIK Bulldozer only has AVX, but unfortunately not AESNI.
