At least there should be no problems with 24x12 on the kernel side,
but this seems to boil down to a problem within consolechars(8) and
the 24x12 (and similar) fonts.
I ran this command line
consolechars -v --tty=/dev/tty4 -f $FONTFILE
with these font files from /usr/share/consolefonts:
Uni1-VGA8.psf.gz
Uni1-VGA16.psf.gz
Uni3-Terminus14.psf.gz
Uni3-Terminus14.psf.gz
Uni3-Terminus16.psf.gz
Uni3-TerminusBold14.psf.gz
Uni3-TerminusBold16.psf.gz
Uni3-TerminusBoldVGA14.psf.gz
Uni3-TerminusBoldVGA16.psf.gz
All of these changed the font.
However, these font files:
Uni3-Terminus20x10.psf.gz
Uni3-Terminus24x12.psf.gz
Uni3-Terminus32x16.psf.gz
did not work, all resulting in the well-known error message:
Cannot (yet) load a non-seekable RAW file
read_simple_font(): Invalid argument
It looks to me that the font files with two numbers in their file name
contain a data format consolechars(8) cannot cope with. This implies
that there is something wrong with either consolechars(8) or the
console-terminus package.
strace output suggests that consolechars(8) does something wrong:
29446 pipe([4, 6]) = 0
[...]
29446 close(6)
[...]
29446 _llseek(4, 0, 0xbfd4ad5c, SEEK_CUR) = -1 ESPIPE (Illegal seek)
[...]
29446 write(2, "Cannot (yet) load a non-seekable"..., 42) = 42
OK, what now? More tests? Reassign this bug to the console-tools
package?
JFTR, the package versions used for this test were:
console-data 20051214 Keymaps, fonts, charset maps, fallback tables for
console-tool
console-setup 1.5 Setup the font and the keyboard on the console
console-terminus 4.16-3 Fixed-width fonts for fast reading on the Linux
console
console-tools 0.2.3dbs-60 Linux console and font utilities

That is different from here: Here, the userspace part of loading the
font fails, probably long before any framebuffer device driver has
anything to do with it.
Gruss,
