Well, in my case that returns 4 stanza's of this:
processor	: 3
vendor_id	: AuthenticAMD
cpu family	: 16
model		: 2
model name	: AMD Phenom(tm) 9550 Quad-Core Processor
stepping	: 3
cpu MHz		: 2210.462
cache size	: 512 KB
physical id	: 0
siblings	: 4
core id		: 3
cpu cores	: 4
apicid		: 3
initial apicid	: 3
fdiv_bug	: no
hlt_bug		: no
f00f_bug	: no
coma_bug	: no
fpu		: yes
fpu_exception	: yes
cpuid level	: 5
wp		: yes
flags		: fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov 
pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb 
rdtscp lm 3dnowext 3dnow constant_tsc nonstop_tsc extd_apicid pni monitor 
cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 
3dnowprefetch osvw ibs
bogomips	: 4420.70
clflush size	: 64
cache_alignment	: 64
address sizes	: 48 bits physical, 48 bits virtual
power management: ts ttp tm stc 100mhzsteps hwpstate

And I don't see anything there that looks like a 'patch level'.
The ucode obviously can, which is what counts in this game of horseshoes.  
Perhaps something in that very long 'flags' string?

Thanks Borislav.

Cheers, Gene
