In general, the mouse drivers do not support SVGA video modes. You can
still use the driver to report mouse movement, but the pointer will not
show.

If you are programming in Turbo C or Borland C, you can use the BGI's in
svgabg52.zip. You can get this at SIMTEL (pd1:<msdos.borlandc>). This
library has suport for almost all SVGA cards and includes mouse support
also (some bugs exist however).
