Keep it up.

I already reported the problem on the dev-list. The reason is that
ConTeXt creates one big table and splits it afterwards in smaller
parts which fit on each page but when you use "split=repeat" the
part for the first page is too large to fit.

Don't use floats in the header or footer, they serve no purpose
and you can include images without it. Below is a solution
with nested frames but you can also use a table to create
the header layout.

Here is a working version of your example but you have to a space
between the header and the page body (see headerdistance setting)
or reduce the height of the outer most frame (it uses at the moment
the height and width of the header area).

\setuppapersize[A4,landscape]

\setuplayout
   [location=middle,
    width=27.5cm,
    height=18cm,
    backspace=1cm,
    header=4cm,
    headerdistance=5mm]

\startsetups[header]
     \startframed[width=max,height=max,frame=off,offset=overlay]
         \startframed[height=1cm,width=max,frame=off]
             \userpagenumber
         \stopframed
         \par
         \startframed[height=3cm,width=max,offset=overlay]
             \startframed[width=0.25\hsize,height=max]
                 \externalfigure[dummy][height=1.9cm]
             \stopframed
             \startframed[width=0.50\hsize,height=max,] % 
frame=off,topframe=on,bottomframe=on
                 some text in the middle block
             \stopframed
             \startframed[width=0.25\hsize,height=max]
                 some text in the right block
             \stopframed
         \stopframed
     \stopframed
\stopsetups

\setupheadertexts[\directsetup{header}]

\startbuffer[tablerow]
     \startxrow
         \startxcell first \stopxcell
         \startxcell second \stopxcell
     \stopxrow
\stopbuffer

\startbuffer[table]
     \startxtable
         \startxtablehead[head]
             \getbuffer[tablerow]
         \stopxtablehead
         \startxtablebody
             \dorecurse{40}{\getbuffer[tablerow]}
         \stopxtablebody
     \stopxtable
\stopbuffer

\setupxtable
   [option=stretch,
    split=repeat,
    header=repeat,
    align=middle]

\setupxtable
   [head]
   [background=color,
    backgroundcolor=gray]

\starttext

\title{Table without float environment}

\samplefile{ward}

\getbuffer[table]

\title{Table with  float environment}

\samplefile{ward}

\startplacetable[location={none,split}]
     \getbuffer[table]
\stopplacetable

\stoptext
