An alternative to `\abs-baseline-skip' is a scaling function
`pt-to-staff-space', see below.  While being more versatile, it's
probably more awkward to use...

#(define-public (pt-to-staff-space size)
   "Convert from points to staff space units."

   ;; The value `output-scale' gives the size (in mm) of the staff space at
   ;; the global staff size.  By definition, the staff space for a staff
   ;; size of 20pt is 20pt / 4 = 5pt.
   (let* ((5pt (ly:pt 5))
          (output-scale (ly:output-def-lookup $defaultpaper 'output-scale 1))
          (factor (/ output-scale 5pt))
          (staff-space (* 5 factor)))
     (/ size staff-space)))


\header { tagline = ##f }
\paper { print-page-number = ##f }

\markup { \abs-fontsize #200 {
            \override #'(baseline-skip . 40) {
              \column { A A } } } }

\pageBreak

\markup { \abs-fontsize #200 {

              \column { A A } } } }
