Well, that refers for the values in that specific table and entire document (which I went through as well) does not specify TjMax :( Similar document for N270 series does specify TjMax explicitly in Table 14: http://download.intel.com/design/processor/datashts/320032.pdf
Another document, "Thermal and Mechanical Design Guidelines" for Atom 300 series: http://download.intel.com/design/processor/designex/320530.pdf specifies Tcase-max = 85.2C Thinking about this a bit, I think Tcase-max should be lower than TjMax, which probably is still 90C. The document itself is a good reading too.
Anyway, thank you very much for your help, Huaxu!
