http://marc.info/?l=linux-kernel&m=130438580705332 says it's a AMD
Athlon(tm) 64 X2 Dual Core Processor 4800+, i.e. a good old K8 desktop.
The X86_ELAN Kconfig option, however, says:

config X86_ELAN
	bool "AMD Elan"
	depends on X86_32
	depends on X86_EXTENDED_PLATFORM
	---help---
	  Select this for an AMD Elan processor.

	  Do not use this option for K6/Athlon/Opteron processors!

	  If unsure, choose "PC-compatible" instead.

so if the sentence before last used to mean anything, this could be a
problem. Quick search about it gives http://lkml.org/lkml/2004/1/12/239
which introduces that different compiler arch for ELAN: -march=i486,
which could conflict with the generic selection?

Hmm.
