For those who are interested, p. 33 of the supplementary material says he was Y haplogroup Q1a.  I hope the 4,024 newly revealed SNPs will be useful for discovering new sub-clades in haplogroup Q.

"The fact that the Saqqaq sample belongs to haplogroup Q1a is not surprising
considering the wide geographic distribution of haplogroup Q lineages among extant
populations in this region. Because modern Inuits, Aleutians, Native Americans and
various Siberian populations all carry Q1a lineages at moderate to high frequencies it
makes this high resolution Y chromosome evidence from the ancient Saqqaq sample –
as it currently stands – non-informative for questions addressing the origins of palaeo
and neoeskimos, and more particularly, about the continuity between the two.
However, this ambiguity is mainly due to the lack of high resolution Y chromosome
SNP data for extant populations. The newly revealed 4,024 markers potentially
include a number of phylogenetically informative markers that, when future
additional Y chromosome-wide sequence data will becomes available for extant
populations, can reveal with higher accuracy the phylogenetic affiliation of the
paternal ancestry of the Saqqaq individual."
