Just a quick check of devices.txt show these floppy formats currently 
supported on a stock SuSE install 

  0 = /dev/fd?  Autodetect format
  4 = /dev/fd?d360  5.25"  360K in a 360K  drive(1)
 20 = /dev/fd?h360  5.25"  360K in a 1200K drive(1)
 48 = /dev/fd?h410  5.25"  410K in a 1200K drive
 64 = /dev/fd?h420  5.25"  420K in a 1200K drive
 24 = /dev/fd?h720  5.25"  720K in a 1200K drive

100 = /dev/fd?u1920 3.5"  1920K High Density(1)
  32 = /dev/fd?u2880 3.5"  2880K Extra Density(1)
104 = /dev/fd?u3200 3.5"  3200K Extra Density
108 = /dev/fd?u3520 3.5"  3520K Extra Density
112 = /dev/fd?u3840 3.5"  3840K Extra Density(1)

 36 = /dev/fd?CompaQ    Compaq 2880K drive; obsolete?

 (1) Autodetectable format
 (2) Autodetectable format in a Double Density (720K) drive only
 (3) Autodetectable format in a High Density (1440K) drive only
   
NOTE: The letter in the device name (d, q, h or u) signifies the type of 
drive: 5.25" Double Density (d),  5.25" Quad Density (q), 5.25" High Density 
(h) or 3.5"  (any model, u).  

Filesystem support is another matter.
