I am running into the exact same problem. I have the hp mini 210-2070 and i am running into the exact same error message when I use iATKOS. Is there a BIOS workaround like for the mini 311.
I have also tried using the NetbookCD 0.8.3 method, however I run into a HFS Signature was not present, can't find mach_kernel. This is with using the retial snow leopard disk.
Any help. i have been searching for days to help solve the problem. It seems that people are able to install on hp mini 210, but I am not sure how they are getting past the usbf ehci controller unable to take control from bios.
Thanks in advance for any help.
