I don't know which machine the reporter of this bug in Debian uses, but I use
Intel Core Duo.

the /proc/cpuinfo says:

flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov
pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc
pni monitor est tm2 xtpr

so imho I do have SSE2.
