17 and this is the kernel you're running?

23 almost identical. The differences shouldn't matter:
24 $ grep -i intel /usr/src/linux/.config
25 CONFIG_X86_INTEL_USERCOPY=y
26 CONFIG_CPU_SUP_INTEL=y
27 CONFIG_X86_MCE_INTEL=y
28 CONFIG_MICROCODE_INTEL=y
29 CONFIG_HW_RANDOM_INTEL=y
30 # CONFIG_AGP_INTEL is not set
31 CONFIG_SND_HDA_INTEL=y
32 # CONFIG_SND_HDA_CODEC_INTELHDMI is not set
33 # CONFIG_SND_INTEL8X0 is not set
34 # CONFIG_SND_INTEL8X0M is not set
35 CONFIG_INTEL_IOATDMA=y
36 # CONFIG_INTEL_MENLOW is not set
37 # CONFIG_CRYPTO_CRC32C_INTEL is not set
38
39 also check "memory split", "Processor family" but I'm just guessing
40 now...

48 I didn't think there should be a difference between 2.6.32 and
49 2.6.32-r1..

54
55 I've never tried. I just edited it by hand (make a backup) and stuck to
56 the new kernel!

58 sorry I'm not much help...
