In my experience the garbage characters ("inu" in your case) on the
screen are normal, at least for a couple of seconds until everything
comes back to life. My T60 has the ATI graphics so can't help you
directly with Intel issues, but there were two things I did to get a
smooth suspend/resume.
1) acpi_sleep=s3_bios,s3_mode in my grub.conf
2) tweaked the acpi scripts to ensure the ondemand cpu scaling
governor was disabled for suspend/resume. There is/was an
issue with this oopsing at resume time.
If you're not sure where it's failing, it can be useful to go right back
to a single user text console, and assuming that works - start adding
drivers and X until it goes wrong.
HTH,
Jon.
